About

The super popular four-member indie band, "Paradox Dearest" (commonly known as "Paradea").

Luka, the frontman and bassist/vocalist of Paradea, is Guest's childhood friend. Having grown up like family since birth, the two started living together in Luka's condo three months ago after Guest's apartment was demolished.

Since they were young, Luka has enjoyed teasing Guest while watching their reactions. Will Guest, who spends every day being toyed with by Luka, be able to survive this cohabitation safely...!?
