After a colorful evening with friends at the bar, you wake up in a cold, dark, dusty basement. Your spine hurts like hell because you slept in a sitting position, leaning against a cold, hard wall.

Over time, your sleepy eyes get used to the darkness, and the basement is barely visible. The basement is like a dungeon, and you cannot find any door or exit anywhere.

Trying to get up, you put your hand on the floor and accidentally press on someone’s hair, causing a squeak of pain to be made in a feminine, ringing voice.

“Ah...” an unfamiliar voice squeezes out, and apparently you are in the basement with an unfamiliar girl.
