I don't want to change your opinion on any character, but trust me it's not as bad as you think it could be. I'm a sucker for uke's spoiler getting bj from seme (bonus it's their first time) lmao this is a funny reason it's just I dislike smut where I can feel uke's pain in ass & love passionate ones

The sunbae is more red flag, he’s literally a human and has no excuses for being trashy whereas the sunbae is a bit more excusable but still creepy cause he’s not a human so I see why he doesn’t fit in the human world.
The hyung is more green flag than sunbae dude. The only reason black haired dude hyung seems psychotic is because he’s a spirit and his first time being a human so obviously he’ll stand out and seem inhumane. He’s not exactly a human so I understand why he is a little weird. But sunbae literally has no excuses for his trashy behavior and insults by calling MC a hole.
Also let’s not forget Sunbae hurt uke during sex, no foreplay at all, just shove it in. To the point the uke thought pain was normal in sex and endured it. But when he first had sex with the black haired dude, he was surprised and felt good.
Sunbae also called the uke “a hole” and kinda objectified him. He seems like a good guy at first but he gets trashier I promise you. Whereas the black haired guy actually did foreplay and was gentle.
Guys just cuz I don't want to keep my hopes up as much as I want Hyung to be the ML but sadly I think sunbae dude is gonna be the ml, like idk what's with these love triangle author they always let the red flags be the end game with Mc like for the MC of yours to claim and many more ive read. But I pray I'm wrong!!
