I just wanna say that beta friend is an unempathetic little bitch.
I know the big Mitsuru=Kuro reveal comes at the end (not a spoiler, since this is my opinion and I don't really know what'll happen), so he can't say anything now but... Apologizing without admitting what you did wrong or the other person even knowing what you're talking about isn't really an apology. Poor Inusaki, I'd be so embarrassed to find out later the person I was confiding in is the one I'm talking about, fishing for information. For shame, Mitsuru!
a "funny" joke doesn't consist of making someone feel upset, even for a short while (I'm aware that it serves as a plot device for Ryuuta to realize his feelings but it's still an asshole thing to do).
Being hurt is no excuse to hurt others. How dare he put down Haruto like that??? Is that what his "love" amounts to? manipulation and cruel words. I hope Haruto, Izumi or both punch him in the mouth.
'Sherlock Bones' loool so great! XD kudos to the author for coming up with that (and the rest of the story ofc) lmfao
Leaving the pill business aside, please use a freaking chair or something to reach high places, especially when you're trying to be sneaky. Then you won't drop anything. XD
