from what I gathered I'm pretty sure yulmu is actually goyo (blonde twin) and not sunyeol (black haired twin) yulmu is from the future, right? But he doesn't have all of his memories so I think goyo dyed his hair back to black in the future and yulmu mistakenly took the wrong twin. And one major reason being yulmu and goyo's personality, they are both impulsive and yulmu and goyo always argue with each other unlike sunyeol who's a good and very understanding guy that has more common sense than goyo, ALSO the events that occurred between them, the only thing that happened between sunyeol and ran is catching her from falling down the stairs (But I don't know if this actually counts bc yulmu possessed him when he caught ran, so it's not sunyeol's reaction but yulmu's reaction) then we go to goyo, he talked to ran the she was upset and got her to open up, then him stopping ran from crashing through the boxes by holding her waist and they had like a moment idk if they noticed it, then goyo simping for ran for a second he she pretended to be nice to him (boi's heart just skipped a beat) That's all. I applaud you if you actually read through this shit
