I think "at the end of the road" could fit right into your criteria. It has the best plot and amazing main characters . Really you should try it if you haven't yet
Golden days
Manga( must read )
Raising a bat (my fav manhwa tbh )
Life senjou no bokura (manga must read )
Hidamari ga kikoeru
Just avoid short, sad and smutty ones. I'm in for any storyrich manga/webtoon with plot and great characters.
