It's about this couple (don't know if they're the side couple of the manga) that has been together since their highschool days. Now, they just treat lovemaking as some sort of exercise as if they've lost the love they had when they first did it. So, one of them tries out different ways to make their copulation more exciting, and I think the ending was they eventually got the spark they lost by thinking about starting a family? I don't remember anymore. So pls help!!
Bruh. The ending better have her be with a man who genuinely loves her and treats her right. Idc if ml here is tryna be nice, he still cheating and using her money ಠ益ಠ
