So Kuga knows that Yashiro loves Kage?

you can see in the last page...when kuga was trying to compete with yashiro, in the sense of who knows kageyama better...or how he laughed when kageyama said "I thought I was more perceptive than this". Before that, he said "without realizing it, you're merciless" to kageyama when kage said he never thought yashiro can fall in love with anyone because yashiro has been in love with kage for a long time and kage didn't realize it.

I dont understand why Kurose said that Shirotani is cruel here?

I think because Kurose also want's to kiss Shirotani so badly but he want's Shirotani to admit it first.. But the later one didn't so Kurose was frustrated & felt that it was cruel of Shirotani to resist this much not concidering how he feels.. *-*

I wonder what he will grow up to be when all adults around him are dating the same sex. ლ(´ڡ`ლ)

he'll grow up the way he want.
you don't become gay just becouse you grow up with gay parents, like you don't necessarily grow up etero if you have etero parents ( ̄へ ̄)

^ This, Oh My God.
I'm laughing so hard right now because it's true.
Sometimes people can endure anything because something they think it is love, but actually it's not. Maybe this story is such a case.
