That was a bad handling on Byul's part, I agree. He didn't say anything and just yeeted out of Dongho's life like that. Dongho knew they weren't blood-related all-along, so he never saw Byul in a brotherly light, which is understandable, while Byul only sees DH in a platonic way, which is also understandable. Byul should have properly rejected Dongho, apologized, and asked to keep distance from DH, instead of just cutting him out of his life like that. Him running away without a proper closure could have made DH feel like being gay was wrong.
I don't think Byul is selfish on a whole, but that was a selfish act.

yeah, I wouldn't be able to take it either, but there are caveats. One, I wouldn't cut my sibling whom I treasure off from my life and acted like he was the plague just because he fell in love with me. I would have properly rejected him and asked for distance. And keeping distance is very very different from erasing an entire existence. Second, I think the analogy of a sibling is kinda wrong because DH grew up knowing all along that Byul isn't related to him by blood. Maybe a close older childhood friend whom your parents treat like a son is a better analogy. Then you'll see why DH is pitiful. No one objects whenever a main character falls in love with the older handsome neighbor next door.
If one shouldn't cut their best friend off just because the best friend falls in love, why should one cut off their own brother?

i'm sure part of why byul minded his crush because his brother is a guy let's say that if the little brother was a girl then do you really think byul will work at some sex motel? when he saw two guys doing sex he said that he could not be comfortable being with gay guys, and how do i know byul minded his brother being gay? the boyfriend of the little brother (i don't know his name i will just call him "the hyung") friend did the same fucking thing when he knew the hyung is gay and has feeling for him, he gone to military service .also if my brother had crush on me i won't dip to gods know where i will handle it like how byul handled it in the end i will know he hates herself enough and confused as fuck and he still a kid so no need to rub the salt on the wound he would move on by the time.
i really didn't like byul i wanted to like him because he reminded me of Eunho from lover boy, but eunho is far better than him, what a disappointment. he is so fucking selfish he couldn't just accept his brother being gay ? did he have to go to military service and ignore him for a year and then work in a gay motel to finally accept his brother being gay ?are you serious? , sorry his little brother was still a teenager at that time he hated himself too no need to be a bitch.and the part where they were both of them in amusement park was pretty annoying,he was being rude i know he just discovered that he is in love and blah blah but that was so awkward and cringy to read, it really not fine to ignore your brother like that i know you don't like your bother romantically but bitch familial love and friendship exist he is your brother give him some attention when he talks to you, i doubt you were best brothers. and it so frustrating to see everyone calling him nice bitch where?he did nothing that nice to anyone i don't know why even his little brother loved him .i'm glad that his little brother started to ignore him in the end. i'm giving it two starts the story wasn't that good, "bl" was a pretty stupid name to give it to a motel.
