not sure why you think her reasoning has changed at all? hyesung and his mother have talked themselves, he gave her a chance to explain to tell him why she abandoned him, why she did what she did. her explanation wasn’t anything justifiable and was built on lies to make her look good, then she had the nerve to say that hyesung didn’t look for her either. the explanation she gave HYESUNG herself on why she abandoned him won’t be any more different than what she might’ve told byul. and no offense hyesung also has the right to be upset, who wants their son in contact with their mother who purposely left him with his abuser of a dad? what they went through is not the same. hyesung wasn’t in byuls life for the two months but the rest of his life he was, hysungs mother was with him till he was a toddler and then left FOREVER - he lit jumped through homes and went through mental scare from his father. again hysung was also freshly 20 and having a baby with a guy he did not know/product of some sort of SA/was not planned/ literally was dirt poor, and not in the right headspace.
Who says hyesung gets a pass. Its because he realised his own mistakes and tried to change himself that people forgive him and understand him. He was abandoned by both parents and abused too. He went through so much. Still he wanted to give the mother another chance but what she did ? Blamed hyesung instead of admitting her own faults. So why would the grandmother be forgotten she was happily living a new life with new family forgetting hyesung. But as soon as she saw he got married to a celebrity she came crawling back not out of guilt(tbh I feel like author will now twist the story to forgive the grandma and make hyesung seem like the problem again). And yeah the new family found out about her secrets and abandoned her that's her own karma. Atleast I think that made her realise her faults otherwise she would just live without a care for hyesung
Hyesung get a pass for everything because he was never in the wrong. And Byul is allow to talk to his grandma but it isn't his rights to forgive that woman for what he has done to hyesung. Hyesung was rape. Got pregnant and dojin paid him to keep byul while hyesung mother gave birth to him and left him all the while knowing that she just left her child with an abusive father. Your words of" hyesung getting is wild" is honestly so delusional.
                                                Agreed!! All people can think about is hyesung’s feelings alone and not byul’s. They forget that THIS is byul’s story now. Readers own emotions take over reason. I say it like this: this situation is very similar to how divorced parents project their bad relationship with their ex onto their child. Banning their child from meeting their other parent and persuading their child that the other parent is a completely bad person. Is not a good thing. Even if let’s say, the mom was cheated on and disrespected by the dad, the child should still have the right to see their father if they want. Because that man may be bad in one aspect like being a terrible lover, but could have the potential to be a good father. And denying your child another person who could love and care for them, isn’t right. 
Don’t get me wrong, Hyesung has every right to never forgive his own mother and not want to ever see her again. But byul’s decisions are his alone. He is his own person and not a doll whose decisions the parents make for him.                                            
                                                Hyesung didn't get a "pass". He acknowledged his mistakes and worked on himself to be a better parent for his child when neither of his parents were any good to him.
Yes, Hyesung and his mom both abandoned their kids but they both knew the kind of man they were leaving their child with, and only Hyesung a barely an adult at the time thought about how the child would grow up in a good environment with a loving parent. 
Hyesung's mom never had any plans to take him or get him out of the abusive enviornment bc she never told her new partner that Hyesung existed and then she went on to build a new family for herself and lived without thinking or seeing Hyesung for years. Then she had the gall to say Hyesung never looked for her. Was her expectation that Hyesung as a child should scour a huge city for her when he had no idea where she was? Atleast Byul had her contact to find her.
And she picked and chose what she told Byul, of her aim was reconcile and atone for what she did, the very first time Byul came to her door she should have told Dojin about it. She is just a horrible and a selfish person.                                            
Hello.. Hyesung was RAPED and forced to have a baby in the beginning.. wtf is wrong with you?? He was traumatized from so much things definitely being RAPED too. He never asked to be a fucking mother at the start. I hate people like you that blame the victim.. seriously get help So yes he gets a "pass". It was never his fault period now stfu
I never said her reasoning has changed? Just gave some perspective as to Byul's motivation for potentially keeping in contact with his grandmother? I never said Hyesung's mother had justifiable reasons, to be honest, what she did was horrible. I think we are in agreement here, but I was referring to the comments here about Hyesung having no faults in this situation and that only Byul and Dojin are the problem here. There are people justifying it was ok for Hyesung to abandon his child, even if it was for a short time, which I completely disagree with, especially since he made the decision to go through with the birth. I also never said they went through the same thing, but they did go through similar things, which I am referring to being abandoned, doesn't matter how long, it did happen to Byul. If I remember correctly they both were in heat/pheromones going wild and both ended up wanting to copulate, even if influenced by pheromones, that isn't SA. It was definitely unplanned, but that doesn't mean not wanting Byul after birth is justifiable simply because he was scared. It affects a child more than people realize. Either way, these are my thoughts and you have free to think otherwise.
I never said the grandma is good or bad, frankly I think she isn't a good person too. She did terrible things to Hyesung, but Hyesung also made mistakes too, like abandoning Byul after he was born. There are people in the comments giving Hyesung a pass, this is who I am referring to. People were saying it was wrong for Byul to get upset at his mom about being abandoned and also people were saying that Hyesung had every right to abandon Byul, even if it was for a short time. People don't realize, unless you study psychology and sociology that the first 6 months of a childs life shape who they are and Hyesung missed on crucial time in Byul's development as a baby. So this is where I have a problem with the commenters. I am not siding with the grandma, but I also am not gonna pretend Hyesung hasn't made mistakes when it comes to Byul. Byul is simply a child but is getting so much more heat than needed.
I have to personally disagree about getting a pass for everything. Hyesung should've never abandoned his kid after making the choice to go through childbirth because people don't understand how much it affects the child. Look after all these years, Byul has kept this all in how it has affected him. Also I never mentioned forgiveness? I am not saying to forgive the grandmother either, but what is wrong with talking to her and potentially getting insight into his own situation if it helps him get some kind of closure as to why Hyesung might've abandoned him for a period of time? Maybe Byul will learn "wow grandma really did some damage to mom, I see why mom did what she did, even though it doesnt justify it, it at least gives me clarity why it happened" kind of thing. Hopefully this clears things up since I'm being so "delusional".
The "pass" I am referring to is people saying that Hyesung has absolutely done nothing wrong and that Byul should be disgusted with himself for ever getting upset at his mom, which I disagree with. Everyone is going to have different view points but I believe if you make the decision to follow through with childbirth and you aren't some drug addict/alcoholic, you shouldn't abandon your child. Also Byul getting upset is perfectly ok, unlike a lot of people are saying. He was abandoned and didn't like that. If it were you, you probably would feel hurt too. So Byul getting upset is valid and I think people are hating on him far too much. Hyesung could've handled things differently. Doji could've still kept the child and Hyesung could've visited, but no he went complete MIA and missed some of the most formative time for a child. I look at this from a sociology and psychology standpoint. People think infants aren't impacted because they don't "consciously remember" the parent not being there early on, but science has proven otherwise and it really affects kids. Just look at how Byul initially reacted in this latest chapter, you can tell it bothered him some and he kept it in all this time. But there are lots of people not seeing this from Byul's perspective at all, especially with him being the child here. Also I agree the grandma isn't a good person, I think we are in agreement here. My whole comment about Byul getting some insight into what happened to his mom from his grandma, might help him understand from grandma why Hyesung made the choices he made to abandon him at the beginning of his life, it doesnt justify it, but it could give Byul some closure and understand the reasoning about his moms choices at the time.

		
All the people here giving Hyesung a pass is wild. I completely disagree with anyone who says Hyesung is not at fault for anything. Byul is justified in being upset after learning his own "mother" (aka Hyesung) didn't originally want him and abandoned him the first few months of his life. Also Byul has every right to talk to his grandmother if he so chooses and I say this because I am sure Byul feels a connection with his grandmother (since I have a feeling) the two of them have probably discussed why Hyesung's mother abandoned Hyesung, which gives Byul an understanding of maybe why it also happened to him for a period of time.
Everyone needs to stop thinking so black and white. These situations are very complex and have a lot of gray area to them.
