what she means:
jkr should have included a redemption arc for draco. this was a boy that was obviously scared of what he was going into, didn't want to be a death eater, and fleed from the war so he couldn't kill anyone. jkr still couldn't include one moment where draco was seen being a regular, nice human being to the golden trio. why did she leave him in our minds as a villain and instead redeem severus "i-got-rejected-once-therefore-i'll-obsessively-stalk-my-old-crush-and-bully-every-student-i-teach" snape?
M: I’m… I-I’m re-really tired please l-let me s-sleep. Let m-me sleep i-it has b-been 2 days… tears are coming out. He’s just that desperate to get actual sleep. He wishes to sleep but his insomniac ass won’t let him
I don’t know about anyone else but I don’t think Sangwoo and Bum’s relationship is romantic or sexual, I think it’s obsessive. That’s what makes it interesting. It’s these two messed up people being messed up together and towards one another (one more than the other obviously). They don’t want to be together, but they do at the same time and it just makes for an interesting dynamic.
