Hopefully webtoons are ok to recommend as well? You might enjoy "Seasons of Blossom" in it's first season, it's a really cute, wholesome romance story but then gets into a lot of other characters lives and touches wonderfully on human connections and depression. It gets a bit heavy starting in the 2nd season but it's still so great!
"I Had That Same Dream Again" is a manga that has some dark references but is ultimately a positive and touching manga. It follows this friendly outcast and her friendship with 3 other women. The art style is also really cute imo, and it's a short read!
I'll add trigger warnings to both of these recs for sh/suicidal discussions
As for recs without any trigger warnings (as far as I can remember! It's prob best to look it up before reading if that's a concern) I'd recommend "Ring My Bell" as a cute, romance manga. "The Greatest Estate Developer" is also a hilarious webtoon if you're looking for something more focused on comedy!
