https://www.mangago.me/read-manga/konya_mo_nemurenai/ this one kind of? idk if it quite fits but it's a good read
https://www.mangago.me/read-manga/the_man_in_the_mirror/ another kind of? he's annoying in a cute way though pfft
https://www.mangago.me/read-manga/juujun_na_omega_wa_yoru_ni_tsume_wo_tate/ this one is ongoing! I really really hope the plot has a satisfying end because it is so interesting and has so much potential
https://www.mangago.me/read-manga/i_m_a_fudanshi_and_my_childhood_friend_is_coming_onto_me/ I personally didn't like this one--it is bully x victim but I skimmed through and he seemed to change for the better? i don't know if it's quite what you're looking for but you might like it
https://www.mangago.me/read-manga/crossing_the_line_1/ and finally this one which is also ongoing, but the love interest pisses me off so much. It has potential though and I am clinging to hope
Bl with jerk seme (at first) but slowly he began to change for the better.
With a Nice progression
Something new or underrated please.
