Iwaizumi is madly in love with Oikawa Tooru. Here’s why (as if you couldn’t already feel the tension around each other)

Iwa-chan is overprotective and gets jealous easily.

He genuinely worries about Oikawa.

He scolds Oikawa when he’s being an idiot.

I feel like Oikawa is the only person that Iwa-chan can fool around with (and they’re each other’s personal punching bags).

Repeat after me: 

IWAIZUMI HAJIME IS MADLY IN LOVE WITH OIKAWA.
