I need recommendations of more mamhwas that capture the depth of feelings like that.

I also need it man. I think some of the earliest webtoons captured depth of feelings. Personally, I found my boo, days of haru, for the sake of Sita, at the end of the road, december rain quite devastating ╥﹏╥ but I'm already forgetting many of them bc i lost the list. There's back to the highteen, Untouchable too.
