I might be wrong, but somehow I feel like the mangaka was implying that Kodaka Sensei was the kid who stole money in Ren's childhood memory. If he was, then he might have some grudge with Ren (or not; Miyuki Abe could be unpredictable with plots).
Can someone tell me simply about whi is kodaka sensei im already read it but ijust dont understand it heheh sooryy ╥﹏╥
