Aiden is an avid fan of the unknown band CHASM. Just before a performance, he witnesses the band’s leader suddenly quit, putting them on the verge of disbandment. “Damn it, how are we supposed to perform without a bassist?” “I-I’ll do it! I’ll play bass!” On impulse, Aiden is thrown in as CHASM’s bassist, but his playing skills are disastrous. Seth, already on edge from heartbreak and poverty, begins acting aggressively toward him, and both their futures along with the band’s fate hang by a thread. “Hey, if you can’t complete that song by next week, I’ll chew off your lips and fingers. Got it?”
