I'm looking for manga with a bittersweet or sweet tone. Examples of tropes that usually have those tones: unrequited love, unexpressed feelings, taboo love, painful first love, etc.

Examples:
Saezuru Tori wa Habatakanai atmosphere/tone here is exactly what i'm looking for
Mou Ichido, Nando Demo. both sweet and bittersweet (sometimes), amnesia has never been so good. the art is fluffy and cute.
Koi Nanka Shitakunai unexpressed feelings
Doushitemo furetakunai hurt/comfort without the hurt
Hatsukoi no Atosaki painful first love
Aiso Tsukashi h/c
Haikyu!! dj - The World On A Palm Omegaverse ^^, unexpressed feelings
