I have an awful theory: what if the blue-haired hyung is definitely a fake, but he's the fake hyung with the strongest feelings for Doyoung out of all the hyungs? If possible, by the end, Doyoung may notice the fake's feelings for him, so he ends up accepting him no matter who the real hyung ends up being?
I had this thought following the chapter where the first fake hyung was killed earlier in the series. Doyoung had such a negative reaction to hyung rejecting his feelings... so what if the real hyung turns out to be one that doesn't love Doyoung? Or at least, the real hyung turns out to not love him as much as this blue-haired hyung does? How would Doyoung react knowing that there is a hyung avaliable to him that will love him the way he wants him to?
I don't think this theory will actually happen, but it's just a thought I had. At least, I certainly hope it doesn't happen Σ(っ°Д °;)っ Nah I don't think this will happen, I have faith in Doyoung to want to find the real hyung regardless of each other's true feelings about each other.
The best friend is very pragmatic and logical, you can't help but feel sorry for him. He's almost like a version of Muyeong if he had denied all his feelings and focused on his status instead. The difference is that Muyeong internally expresses himself, and on the completely opposite scale, Seonho externally expresses his feelings, which is why they work so well as a couple!
Though the dynamic between Muyeong and his friend makes sense, considering how mature and rational they are together. They only draw more attention to how much Seonho puts his emotions on his sleeve, which brings out the passion in Muyeong more. This is definitely proven in the last two panels of the recent chapter~
This is hilarious and I love it
