The Devil Finally Rocks summary:
Dowoojin, a bassist in an indie band, was a bit of an oddball with a dark side. He was always extremely unlucky. After his band disbanded for the second time, leaving him nowhere to go, Dowoojin finally got a third chance. In his new band, he met Heesoo. Heesoo, who had lived a very ordinary life, with his biggest rebellion being a five-pointed star tattoo on his arm, found Dowoojin strange and hard to understand. After band practice, during a noisy after-party, Dowoojin, who had been giving short, awkward answers to everyone, noticed Heesoo’s tattoo. "...The pentagram symbolizes the devil." A peculiar gleam appeared in Dowoojin's empty eyes. Just then, Heesoo remembers what a bandmate had mentioned when introducing Dowoojin. "I told you, didn’t I? That guy’s seriously crazy."
