Review Detail of pkoopmanpk in When I Saw The Returns, I Invested In My Future Wife First

I like this male MC focusing on one love interest story. I've seen more of these from a female pov, so this is kind of refreshing. And most of the male variants focus on harems with girls that love the MC for no reason, which I dislike. Does anyone have suggestions for novels like this "Male MC, one female love interest"?
