It's just my opinion but I think Haru is so selfish
He don't let Ren spend sometime with his friends and gets jealous like yeah I don't let anyone stay around you...
Like when they wanted to buy shoes or when Mika came to their house and he didn't let Ren got field trip alone despite how much everyone told him he mustn't....
But Haru himself let women touch him or if they wven want to hug or kiss him he doesn't care that much
I think it's a bit too much like dude Ren isn't a kid he is already 17 . Sometimes I think Ren's been putting up with him and he's enduring Haru's selfishness
Anyway it's just the way I thought so don't fight me #-.-)
Just by looking at his face in last pic made me realize he seriously needs a therapy !
You just realized that, deary? LoL.
