Please stop hating on him, the fact that he did that means this story is that close to reality. I (Male) once fell in love with my best friend who already had a girlfriend at that time, because of pandemic we haven't contacted or seen each other, we didn't even hang out. After those years we've seen each other again and we've gotten closer than before, his girlfriend probably knows I like his boyfriend since I was being obvious but I did not overstep any boundaries. Our closeness was special, he sometimes would invite me to play games with him rather than go home together with his girlfriend after school (he already asked his gf about it), he was clingy, there are moments he would stick to me like glue. Sometimes I would have to draw the line between the two of us since he has little to no sense of boundary and I don't want to get on the bad side of his gf as she looks fierce and is our vice president in class, also the 2nd most intelligent in our batch. She confronted me that one time, she asked if I like his boyfriend and that she wouldn't get angry at me if I do, since I've already been obvious, I said yes I do but I won't overstep my boundaries and be a homewrecker cuz I'm not that type of person. After a year, I've sorted out my feelings for him and that was the time where I can freely and I freely said to him that I liked him for the last 3 years but now I'm over it, of course he was shocked like his bestfriend for years liked him this whole time and at one point he might've felt betrayed, though he didn't say anything to me but say that he really didn't expect that to come from me.
In mc's case, the ml like him but doesn't realize it yet, he's oblivious to his feelings. He liked a person for (I believe) 10 years (correct me if I'm wrong), like he "likes" the person who possibly could like and not like him back so he ran away because he got engaged, it would hurt him if he sees the person he likes for how many years get married, he ran away to stay out of trouble. Unfortunately, ml chased after him so things became messy. Obliviousness is the ml's fault for getting engaged with Gisella while not realizing his feelings for mc. Gisella wants mc to confess his feelings to ml but you should know it is very hard (as I have gone through it myself, I was only able to do it because my feelings for him was already gone) it isn't as easy as saying "thank you" to people who've done good deed to you. Mc has an option to protect himself, to be selfish, because that's what being human is, we humans are selfish, we protect ourself because of our pride, someone might say that they're not like that that they're not selfish. Selfishness is in many ways, you could've been selfish without knowing it, I know that we all have become selfish even just one time to protect ourselves.
Also, I believe it's not always that we should forcibly make the person realize. There are times where we need the person to realize it themselves. ML needs to realize it himself, because all this time he's been hurting two people because of his obliviousness to his actions. He's been hurting these two people without knowing it. What hurts the most is getting hurt by the person you like the most but they don't have any idea that you were hurting. What hurts on the other hand is when realization hits that you've been hurting the person you care for with the actions you've been doing all this time. Also people might say "Why doesn't he tell him that he's hurting so they can resolve it", it's just similar to how we've (not everyone) been hurting but we don't tell our parents about it. Just like I said, mc is being selfish and he has the right to be, because it isn't easy, we can see in this chapter that he's always contemplating whether to say it or not, and he chose not to. I believe Gisella will be the one to say it to Ml, if he doesn't realize it himself. (〜 ̄△ ̄)〜

I have this feeling that the assistant and the brother is a couple, or maybe fuck biddies cuz the way he acts is like too full of himself like he knows whatever he does he will have the brother's favor. It's just a feeling so it might not be it. Also I don't really have anything against people who liked his brother because that's their preference. However, he might be handsome but his personality is not so it (I can't really say much since he only appeared in like the latest chap so we need future chaps to really analyze his personality). I guess I'm the only one who dislikes his brother, I like his face, his aura, and I know he's just doing it to "protect" his younger brother though he could've talked to them first (like together with the three of them facing each other) rather than possibly forcibly ruining their relationship cuz he really gives off the vibe of wanting to monopolize his brother's interaction with people and relationship.

Finally. Someone finally said it. I had the same thoughts, like, sure the brother is hot and he might be doing that to protect Ayumu, but that ain't the right way to do it. He's deciding for his brother, and that's a no-no. If he love and respects his brother, he should talk to his brother and his lover without prejudice or something.
