uhm maybe Lost in the cloud, Ao no Flag, Between the lines, Checkmate....?
Degenerate, Things that deserves to die
Where the dragon rain’s falls
Eighteen’s bed

https://www.mangago.me/read-manga/passion_raga/ (this is a spin-off sequel of PASSION, I couldn't get into Taeui's story but Xinlu (liked Taeui in PASSION) & Yuri (our MC in Raga) are so yummyyy)

You can read Passion Raga as a standalone, I didn't & don't want to read PASSION
looking for stories with complex characters, maybe the MC doesnt start off with the ML but slowly falls for another???? or something full of drama but consensual even one could be a player lol
