Kai is a seemingly normal teenager. And he would be, in fact, if he didn't always have Coolman by his side, a hero only he can see who constantly entangles him in compromising situations that lead to disaster. But it's never Coolman's fault! With a weekend ahead without his parents, an older sister planning a spectacular party, and a school costume party where Kai is supposed to go dressed as an eggplant, there's only one thing our protagonist can do: emigrate. Or face the situation bravely... and with Coolman!
