Tokyo: I Took In My Ex's Homeless Twin Sister

Reborn in Tokyo with memories intact, Sawayama Haruno has it all figured out—ace student at Asia's top university, future literary plagiarist extraordinaire. When his belated cheat system finally arrives, he just laughs it off. Too little, too late. But then the system drops a bombshell: his next-door neighbor is his ex-girlfriend's twin sister, the girl who almost became family, now facing homelessness. Armed with a wallet full of cash and separated by only a wall, Haruno faces an impossible choice. Save the girl who shares his ex's face, or let fate run its course?
