This manga has nice drawing, and started with an interesting story (a divorced female lead character learning to love herself). But now it’s too much drama.
I justify some of Kazuki action as misunderstanding issues, but now...
Dude, you finally solve your relationship with Choko and now you asked her if you could sleep with other woman... to make it worst, her best friend.
And Hanae should learn about boundaries, that comment was out of line.
Both are emotionally manipulating Choko.
And Choko is so naive...
I wish for another male character who can love Choko unconditionally and Kazuki realizing that he fucked up his relationship.

I think it's a redemption opportunity for the bully. I remember that the reason why he bothered Mr. Jin was because he misinterpreted his refusal to hang out with him (I'm not justifying it, but it did not come from hatred or idleness as the bully girl). Also, Mr. Jin would get the apology he need.
My evil self wants some cliche for him (to fall in love with Miss Haena and then suffer) but I do not know why I'm shipping him with her sister.
PLEASE JUST BUY A DAMN LUBRICANT!!!
He will, once they run out of olive oil :P
