Yeah I don't know how to feel about this one. I guess we just assume that the older brother is supposed to be hardcore and yakuza like or super protective of his sister...but this is way too much. I mean, most guys would just beat him within an inch of his life for hitting his sister. Im enjoying the manga but I just feel like there are some flaws in the writing...
Yeaaaah... But there's also the fact that the Yakuza bro had some sort of crush on Yoru too and saw him when Asaichi ran away (ya know, when he (Yoru) was all dishelved and whatnot after giving a bj). Doesn't mean he had the rights to go THAT far to be less frustrated about the situation though. Oh well, I'm still gonna read it to the end cuz anyway, I've seen so much messed up shit (and even worse...) so at this point whateveeeeer Oh and you can understand the Yakuza bro's (kinda) crush on Yoru by reading the prequel: http://www.mangago.zone/read-manga/aru_otoko_no_uta/
OK SO I UNDERSTAND YOU BEAT UP THE GUY WHO HITS YOUR SISTER BUT RAPE AND YOU WANT TWO MILLION JESUS SHE MUST BE AN ANGEL OR ONE HECK OF A SISTER BECAUSE I UNDERSTAND TWO THOUSAND OR PAY HER HOSPITAL BILL BUT COME ON!!!!!!!!!! THIS MANGA IS STILL THE SHIT (MEANING BOMB) AND THE TENSION IS REAL
