My guess at suos reasons for recent chapters
Ok so while guessing suos backstory I had a thought as to why suo left school outta the blue and beat nerie up, what if hes trying to protect nerie from a rival gang or mafia.
Since the RC seems to be alot bigger then furin both in size and issues they face(suo saying hes good at integrating other makes me think that their not that clean with their methods of protecting the town either), what if the actual mafia or yakuza was their rival gang.
I think suo was just a random kid who got trained by his teacher who happened to be one of the three dragons at the time, suo who looked up to his teacher ended up getting wrapped up in with the RC and became an unofficial member at that time
Later when he was younger, (a little bit before middle school) he got kidnapped by a rival gang/mafia and tortured him by cutting out one of his eyes and beating him senseless ( the reason he doesn't take off his shirt is cause thats where his scars are). His teacher ended up rescuing him but felt guilty cause the reason that happened to suo is cause of him being close to his teacher
His teacher and the gang decided to send suo to furin to keep him safe for awhile till they think its safe for him to come back (unrelated but I do think suo is spoiled with the other members, he just reaks of younger sibling energy who gets away with everything) and when suo reliazed that he came to love nerie (for the sake of this theory platonically) he decided to cut nerie off before he suffers the same fate as suo, and beat him up as a sure fire way for nerie to deem him as a lost cause and to give up looking for him
