Don't be afraid, I've truly come to bring you happiness.

In reality, Lin Yuanshan is a gentle, kind-hearted man with the nurturing soul of an ideal partner. But inside the life simulator, he is a criminal mastermind endowed with terrifying brilliance. When forced to cross over into an alternate Tokyo, his mission sounds simple enough: bring true happiness to troubled young girls. Yet, staring at his target’s rock-bottom happiness rating of minus-fifty and her eyes wide with absolute terror, Lin Yuanshan falls into a profound dilemma. "Would you like me to permanently eliminate the people making you unhappy? Buy one, get one free!" "Or perhaps you’d prefer if I forced the songwriter to work exclusively for you?" "Don't worry, the police officer tied up in the trunk is just taking a very temporary nap..." Faced with echoing screams and the wail of approaching sirens, Lin Yuanshan can only raise his hands and shout in desperation, "I swear I'm not a bad person! I genuinely just want you to be happy!" Trapped in an endless loop of being plowed down by dump trucks, fleeing from relentless patrol officers, and utterly horrifying the very girls he is trying to save, Lin Yuanshan sheds the tears of a truly misunderstood, gentle soul.
