Death Candle: Jugeumui Jibhaengja

Please, help me die!
Sick of living, Mimi has tried numerous times to take her own life. Much to her dismay, she somehow always ends up surviving. But then she comes across a website called "Death Candle" and ends up signing a contract with a demon of death: if Mimi helps him collect souls, he'll help her die.
