I can understand the issues with the plot and all. In regards to the wife knowing her husband sleeps with other people. There are people that have those types of relationships. There isnt anything inherently wrong with them if they both agree. Isnt it better for both people to agree than one person or two cheating?
Well, these guys are yakuza, so morals are just a hassle. And it was hinted at in the earlier chapters, but Ane-san was a prostitute. Though their marriage is of convenience, both Ane-san and Boss love and respect eachother. However, Ane-san knows the boss can't be tied down, and she is willing to share.
Also, I agree, if Rogi were a women, for sure she'd be called a bitch, slut etc. This double standard is effing insane.
I forgot to add this: But Ane-san's profession as a prostitute sheds some light into why she didn't bat an eyelash to her husbands affair. After all, prostitutes are often coerced into unconventional relationships.
I really hate this story. I coudnt even read properly.. I only see rape,scam.. especially how can someone sleep with married and have child man??? Even his wife know! And how her didn't kill him I am shock... really I really didnt like this plot. I don't feel that guy really like someone... if one women do it manga everybody say she is butch,assume but whenever man do it he has a some reason! He has a trauma Tec!
