Just finished reading this masterpiece after putting it off for months. 1. I can't seem ...

FIY, they never been raised as a step brother and sister. The chairman was acting as his guardian. And they met when the guy was in high school and she was in middle school. And they were never been raised tgth. Pretty much went their own lives. And to me he should be the ML. He cared for the actual Sera but Sera's hatred made him hate her but he never genuinely hated her and fall in love with the FL. On the other hand, the fiance is more like a partner and wasn't really good to real Sera (which really hurt me) Even though real Sera loved him and always trying protect him but he was narrow-minded guy.
And the Blond one is more like a supportive friend. Wouldn’t want him to end up with FL. He needs therapy not love.

I think you mean fyi (not trying to be rude or smth).

1. They indeed were raised as step siblings (you can still be raised like step siblings even if you hate or don't interact with eachother, ex: Cinderella)but mc and the mother didn't acknowledge him. Yes I do know the chairman raised him like he was his guardian (sponsor/patron?). Idk why you mentioned the timeline when he was kinda of adopted by the family since it's not really relevant. Yes, he did care for og mc and the present one but I disagree that he started hating her when she hated him, I just think he started becoming more self aware of his place and viewing her as a opponent to take the company ( in my pov he didn't really hate her and suppressed his care for her). It just irks me a little, I wish they'd continue with their brother-sister relationship (like he looks like the cute younger brother)

2. I'll that you meant that the fiancé is more like a company partner (formal platonic way). I understand he wasn't a good partner but the development he made was a big change. (they were in a contract relationship, which he was kinda forced to accept to solidify his position within the company, mc was also really broken at the time and needed someone to rely on) He was cold and harsh with her which doesn't sit well with me but mc was making trouble and he was the one to clean after her and that could be really exhausting so I think he took his pent up anger on her and stuff.

3. who says blondie can't be in therapy and have a romantic partner? (Lol) Yes he is mentally unstable (stable with mc and some other exceptions ) and I do agree he needs therapy, to some extent (BC of mood swings and stuff) , but let's not forget he was diagnosed at a very young age so he is kinda self aware. I support this ship (mc x blondie), as I've said previously, bc I'm a sucker for cringe/classic tropes (aka "I can fix him") and mc did indeed fix him like he went to work (kinda was a big step for him) and was looking forward to living. (unlike the pov we saw in the days before he met mc) He was a suicidal guy and she was his will to live again. (He kinda looks the type to earn and yearn, lol)

I agree with you in every point and your choice. Totally reasonable.
But for me, Ro-un is better choice for the FL. If it was real Sera, I would have said brother-sister relationship fit best for them but not for FL. I feel there is spark between them and it was Ro-un who always come to save her even after they were just trying to kill each other 'before' (kind of). And as I said he never really hate kind of hated her, he just wanted to survive but never really trampled over her or hurt her feelings like the fiance.

Now, lets talk about fiance. Yes, real Sera made trouble but he could at least showed her some concerns when she was getting hurt left and right. The real one clearly said how nonchalant he was when she got hurt and instead of hearing her he was scolding. It was after MC possessed and communicated with him then he understand his mistakes or else he wouldn't. So, he better stay with her as a business partner. He is a good guy, it is just I don't see any spark with him and his past action don't really make me root for him.

And the blonde is purely your personal choice. I don't oppose the romantic relationship but it feels like he is better as a friend who MC supports. And don't forget MC don't really like his maniac behaviour.

Btw, about the adoption. There is a thin line difference between adoption and acting as guardian (which is also known as fostering). He wasn't adopted into Shin's family rather was fostered by chairman. And if we look at real life situation, it if pretty common in chaebol family to foster orphan boys and then marry them to their daughters so that the assets can stay in their family. Guess, I am not oppose to that kind of scenario.

Ye I do know that he wasn't adopted that's why I said "kinda of". You rooting for the brother and mc also implies that it's your personal choice. (I don't mean to offend but when you wrote that about my choice it kinda sounded undermining, I'm kinda sensitive and reading stuff can depend in the tone you read and stuff)

I do think the brother is endgame/mml (still rooting for blondie tho), yes I do agree that if it was the og mc, they would be better as siblings but their relationship has changed and after knowing that they aren't blood related (and seeing that scene which both were blushing) I, and others, can conclude that they have romantic feelings for eachother. (but don't know about their existence, only the mc tho cuz he already seems aware of his feelings or it's just a matter of time)

I do think the ex fiancé has already fallen for her or just thinks "she's changed". I hope he doesn't turn evil or interferes with the main couple. If he turns out to be the mml I'm just gonna crash out.
I can see why you think blondie is better off as a supporting character rather than endgame. (which I completely understand and it really makes sense)

y r we referring to him as the brother did we read the same thing or what? did u miss the entire segment where he literally says he was isolated from the family and felt completely left out of the family dynamic? even if him and sera WERE raised like family, that has little to nothing to do w our new sera. she only starts treating him as "family," taking him out to eat and bonding w him because shes actively mending sera's old relationships, not bc she actually sees him as a brother- as we can clearly tell by her catching feelings super quickly. granted, it would be weird for him to like her if they were raised as family, plus we already know isnt the case. I would also mention the fact that theyre not even remotely blood related but I understand family can be deeper than blood ties, but I dont think thats their case.

Did you read the other replies? Most of them mention the same thing you do, in mine and theirs responses. Yes I'm referring him as brother/ step brother bc I couldn't remember his name ( it's not like I still believe they're step siblings and I pretty much did show that, so why are you coming for me?)

yeah just read ts, ur switch up is crazy to me, but as long as u understand ig
