The other partners being cheated on for pushing the MCs to feel that way suck the most here. I don’t understand You and I feel like he doesn’t actually love the female MC, he just wants someone to be around so he’s not alone, like a caretaker of some sort. Niina’s wife is just inconsiderate af, she can’t be thinking that her current hierarchy of priorities is sustainable for both her work and personal life. Thus, idc that the MCs are mistaking their feelings. It’s cathartic for them, a release of years’ worth of neglect and pent up feelings. Idgaf.
