You're sure asking for a lot /j
https://www.mangago.me/read-manga/mousou_telepathy/ -straight, been a while, but it's a romcom manga lol.
https://www.mangago.me/read-manga/the_devil_s_temptation/ -BL (it does have a love triangle, but it's obvious who MC ends up with. Been a while since I read it, so I don't really remember the exact elements.)
https://www.mangago.me/read-manga/sign_language/ -BL, has slight dark elements, but nothing too bad
https://www.mangago.me/read-manga/semantic_error/ -BL (I enjoyed this one so much that I got the physical copies 'v')
https://www.mangago.me/read-manga/the_double_life_of_the_demon_king/ -BL, on the kinky side though
https://www.mangago.me/read-manga/motto_musunde_aite_waya/ -BL, also on the kinky side
I thought I had more stuff than this. Mangago deleting lists a few months back sure did a number TvT
