Secret Partner ( Manhwa Porn )

This one is weird cuz everyone is selfish and fucked up in their own way and its weirdly trying to play off a victim situation here. 2.6/10, now i will get into the spoilers. The first guy cheated on his gf played victim left her alone(good reason but like too far) and then lived like the biggest incest, the gf falsely said 2 people raped her lied to her bf and then got together with the other “rapist”. the mistress/secondgf seduced this guy got him into a fight with his gf then gave him a hint of “lets go out” TWICE and then left his life forever without telling him even her name. Fucked up story dude idk why its told like the mc is a victim here, gives me a vibe that maybe something happened(not as extreme) irl which made him write this.
