I didn't know what exactly to call them, lol [@tatszico] :')
Maybe they have a thing where they're like, actually friends, and hang out after sports meet on a particular day of the week?

(Since he's a third year, Tak probably will interrogate him a lot about Shiro... "what does she like? What is she like? Does anyone like HER?  Who? I'll punch them in the jaw, I will, god...how dare they," and just get general convo going.)

Mmm delicious character interactions.

EDIT: I just saw your edit oh gosh xD Internal jealousy festers.
