love this perspective… i think everyone thinks it’s jaewon bc of the mole placement ! Also there was another moment (i forgot the chap) that seo-in came back to YW house after he returned the switch… and i believe yoontae confronted him and said what are you doing here… it seems like from that yoontae was not super involved with seo in

but that was the brother he had the same mole and hair color ,the brother kissed him to drift them apart , i think he called yeongwoon on purpose to meat up at that class room and kissed Seo in knowing he'll see them ,to break them apart , the brother dosnt want Seo in to have anything good in his life"remeber how he destroyed stuff his mom gave him" this is the same case , and he probabaly ploted all of this ,he knew how much he loved and cared for yeongwoo being over protective over him and that they were hooking up.

I looked through the author’s notes and didn’t see any mention of that? It’s hard to be a mistake when they did it twice in the story. They showed the same kissing scene 3 times in the story (chapter 1, 2, and 20). Two of those times the mole was on the wrong side. One of those times the mole was gone and there was an added image on the side of them supposedly smiling (which I honestly believe is yeongwoon’s imagination since it isn’t the first time he imagines seoin messing around with someone)

Ohh so you meant a tweet and not an official authors note included in the manhwa. Yeah I looked it up and the author tweeted on March 14, 2024 “ The location of Seo-in's dot in the flashback scene in Episode 1 is a mistake I'll fix it as soon as I have time!! Thank you for the tip.” So I guess chapter 1 was a mistake on the authors part and they fixed it in chapter 2, but then the author used the same art mistake in chapter 20??
Idk, hopefully the oncoming chapters of seoin’s pov clears it up. It is odd that the author messed up twice lol. I wish the author mentioned that mistake in the official authors note instead of some reply on Twitter lmao

I'm fairly confident it is Seo-In and the brother, and my theory is that Seo-In actually actively kissed Jaewon. The art shows him taking an active role by grabbing his brother's shirt. My guess is that Seo-In was trying to trigger/upset the MC. We see that even in the present, Seo-In regularly flaunts his sexual escapades to trigger the MC. In the past, he's also frustrated that the Yeongwoon doesn't seem to be as into him, and then suddenly an older guy comes along and there's not much Seo-In can do to intimidate him like he can his classmates.

Actually, I retract what I said and I now fully believes that it was definitely the twin lol. But I have my own theory as well, I feel like it was Jaewon's idea, I think he blackmailed Seo In to kiss him because he knows that he is Seo In's weakness and deliberately taunts them both and we all know that despite SI's effort to reject Jaewon, he's still has power over him. I also think it was his way to lure YW to beat him up, but we also saw that he beat up Jaewon's ass in that flashback.
Idk, I got a feeling that the bitch died after that incident and that's also the reason why he got anxiety disorder. He probably died after Seo In went abroad.
New theory, what if the one Yeongwoon saw in the classroom kissing was Seo In and the bullied kid (forgot the name already)? A lot of 'theorist' believes Jaewon kissed Seo In and that's when they drifted apart but it wouldn't make sense cuz YW knows that Seo In and his brother were not in good terms and why would that upset YW anyway? So for me, it's plausible that it's the bullied kid.
