If you know you can't be/won't be monogamous, or that you don't do well in serious relationships, don't make promises you can't keep. Megane can chase all the dadbod dimwit dicc he wants, but to do it after supposedly entering a committed relationship with someone else is selfish and just plain cruel. Mita is an idiot for forgiving him and trying to force him into a role he is ill suited for, but the other guy whose name I can't be bothered to remember is the instigator of the overwhelming majority of their negative interactions and problems.
