Help I guess T_T

So I’m searcing a specific manga, kind of 201~ old, about a high school girl who’s in love with her teacher and it’s kind of mutual but he can’t but you know. I think, and now it’s where I’m not so sure, that the manga give kind of the same vibe as this one: https://www.mangago.me/read-manga/akuma_to_love_song/

Maybe I’m wrong and I’m mixing everything idk, the graphic could be TOTALLY different it’s just…a feeling…idk guys
I can only add that the girl is confident, in a cool rich way and yeah…
If u find it THANK YOU but my brain is probably just mixing everything oops （/TДT)/
