this title and the title with the childhood friend who cheats on MC and then experiences an Apocalypse of Consequences feel quite similar.
Two different premises, but both have, like, two different stories of two disparate genres, smashed together into one narrative.
That one has the Supreme Revenge Plot against the childhood friend, her NTR partner, and then all of the bullies; while the ML and FL both get to experience a delightfully slop-filled SoL Romance story where all their suffering at the hands of the first batch of characters is erased once they find true love in one another, and they are largely separated from the goings-on of what transpires for the Consequences Portion of the story.
This one has the MC snap on his abusive childhood friend and go his own way, collecting a harem of girls while the CHF goes batshit insane over being relegated to the dustbin of dumpsville, and he's also an S-tier martial fighting super genius who takes on what appears to be a criminal empire organization of scaling power levels of baddies, likely all brought to bear against him by the very family who raised[indoctrinated] him. No clue as to whether the Harem gets fully involved in this, but currently they seem fairly separated from whatever the CHF has cooked up for the MC.
Just interesting that they're running concurrently and are both reasonably popular "new"-ish series this year.
