Here is my recommendation:
https://www.mangago.zone/read-manga/eternally_regressing_knight/
https://www.mangago.zone/read-manga/heaven_can_t_live_an_ordinary_life/ (first 17 chs kinda rough but there will be a change of artist after that)
https://www.mangago.zone/read-manga/i_m_not_that_kind_of_talent/ (umm, it is funny but it will be kinda dark later.)
https://www.mangago.zone/read-manga/black_haze/
https://www.mangago.zone/read-manga/the_100th_regression_of_the_max_level_player/
Read if you haven't yet! ^^
The only one I haven't read is the 3rd, I can’t handle siblings angst, too much for me
But thank youuuu tho I rly like the other ones you recommended (づ￣ ³￣)づ
Something similar to https://www.mangago.zone/read-manga/surviving_as_a_genius_on_borrowed_time/ or https://www.mangago.zone/read-manga/absolute_regression/, cause I liked that the first one had no regresson or anything like that involved, and I also liked that the second one was pretty funny
Either way good art is a need pls
