waittt I’ve read both but like what is their similarity? aggressive seme?

No, i just really their plot (๑•ㅂ•)و✧

like*, i don’t think their similar

okkk i see, well something similar to monochrome rumor, in the aspect of idols/become an idol in your second life, you can try:

https://www.mangago.zone/read-manga/meteor_orbit/ (is the only other good second life idol bl)
>non bl ones, which are better plotted amongst the other second chance idol ones:

Monochrome rumor: as for the uh gangster/mafia MC swapping bodies with another person, there's this (action-based):

Uhhhh as for jinx...
in terms of a boxer main character, all i can think of is this:

but as for the toxic seme, there's a lot ahahah - tho one that i remember on top of my head ig (only if jinx's storyline goes along with the same route of BJ alex, where ML just uses MC, MC falls in love , confesses, then gets rejected, and then ML regrets and tries to get MC back):

it's kinda hard finding things that are kinda really similar, cuz i think their concepts are pretty new-ish (or maybe i don't read enough ahahah)

thank u so much! ٩(๑❛ᴗ❛๑)۶

hope it helps a bit ヾ(❀╹◡╹)ﾉ~
