Rinko, again, more mature than any character introduced so far.
Yes, you're an idiot. Congratulations, you played yourself.
Cutting yourself off from a person who dumped you, that gave you emotional support in the time of need, although Haruno has attachment issues, is quite normal.
Then Koyori searched and stalked Haruno because life without him lost it's meaning, up to the point of suicide. Should talk it out instead doing a "test of obedience".
Koyori has issues, self worth is a main one, although she made herself "pretty", it's because she felt like an accessory to a fine looking man.
There was absolutely not a single thing wrong with her back then, he was staying by her obviously for money, "she was fine as she was".
Rinko mom most likely won't return, Haruno is right, they should live together and work their issues out.
Heck, even marry Koyori and adopt Rinko, her mom doesn't deserve her.
Thanks for scanlation!
