yeah, that sounds good! he'd probably talk to him and ask what's up. whether he tells him or not prior to quitting is totally up to you, but i think if he doesn't, it'll give them a chance to hang out since he quit to catch up and see what he's been up to and find out what he does now/had started doing back then. he's also childhood friends with ~enchantor and friends/biker gang buds with ~gajima.
