I am copy pasting my comment haha but SPOILER (ignore if you don’t want a summary lol)
So the real reason the seme liked the blonde guy is because he thought the blonde guy was the child (red candy Sihyun) from his childhood who he bonded a lot. It was Sihyun he liked all along without knowing it. They both got into an accident and he forgot some of it even the face of the child but he remembered Sihyun had blood on his wrist before he passed out. So after getting out of the hospital he assumed it was the blonde glasses since the blonde had a scar on his wrist. He forgot the face but he remembered the bloody arm. The blonde dude and the seme met right after the accident and Sihyun never showed in front of him again so all this time he thought it was the blonde.
The seme regained his memory around chapter 52 and remembered the face of the child (Sihyun). At chapter 56 he did the thing again when they were children, where he wrapped the head of Sihyun with a cloth, to the present sihyun and recalled the past again. I think he already knows the kid was really sihyun and not the blonde at this point. Idk if the blonde also likes him. He shows up a lot now and keeps remembering the past too with the seme.
One thing I can see is that the seme is now crazy for the uke (red candy) lol. I think he likes him so much lol judging by how he looks at him in the raws he looks at him with so much love. When they have sex too it’s so much different the first few chapters. He blushes like crazy now haha. But as of latest chapters when the seme does that(look at him sweetly), the uke remembers the time when he saw the seme hugging the blonde glasses in front of the house (it was a misunderstanding he was just comforting him because of a car crash lol) and he gets sad and hold his feelings back. I didn’t like it when the uke run away after seeing them hugging and went to the blonde agent. Sihyun got drunk and they kissed. They didn’t have sex though and the blonde sent him home instead of letting him stay with him. I like how the blonde agent did not grab that opportunity to sleep with the one he likes lol. I really thought he was gonna be like that. Anyway that scene Sihyun witnessed created necessary misunderstandings and by necessary I mean I think it was good because it opened up a lot of things they needed to know about each other (and things we wanna know too hahaha). Some they still need to find out together. Mostly on Sihyun’s part since he still probably think the seme is inlove or something with the blonde glasses lol and he still doesn’t remember the seme (i think at chapter 60 he did slightly.) I mean dudeeee look at how he looks at you it’s so different from how he looks at the other guy. And his sweet kisses (づ ̄ ³ ̄)づ he’s inlove with you.
