When the average man is suddenly thrown into a video game as an extra, fated to die, they might first think to hide or run away. But not Luka. A man now inhabiting the body, he simply wants to survive - no matter the cost - even if it means he has to kill the main character!

[Harem Heaven High School (HHHS)]As the name suggests, it is a dating simulator that gained popularity due to the beautiful heroines with huge breasts and, more importantly, the importance of the player's choices, which influence the endings.Zayden Valtrex, the son of a billionaire philanthropist, was a feared delinquent at Eiko Academy. Standing at 1.95 m tall, with blond hair, full of piercings and earrings, he even scared the teachers.He was none other than the great villain of HHHS, who stole the heroines from the protagonist Subaru Kisaragi.But one day, that very same villain suddenly shows up at school with a completely new appearance. He had removed all his piercings and earrings, changed his hairstyle to be slicked back, and wore a charismatic smile, no longer looking at others with that usual cold stare.Since then, more and more heroines began approaching him of their own will.What no one knows is that Zayden carries a secret memory: he is not only the villain of the game but also someone who once lived in another world... and knows every detail of HHHS. Moreover, he possesses a mysterious system: by spending money on a girl whose affection level is above 50, the return can multiply from 1 to 100 times — and it is not limited to money alone.

After the hard struggle of a post-80s Shen Feiyang, he met with a tragic car accident in his fifties. When he again opened his eyes, he did not see the white walls of a hospital, nor had he arrived at the netherworld. Instead, he had transmigrated into the body of the post-50s young girl, Shen Yunfang.He had transmigrated into an era where people could not get enough to eat or sufficient clothes to wear.Humph, such hardships could not defeat a wise woman who had battled through society for half her life. Watch as she, with a chicken in her left hand and a duck in her right, carries a chubby baby on her back and sings triumphantly along the way.
