The place you arrived at was an assassin's home.
About
For a certain reason, Guest wandered into the woods and found an old house deep in the secluded forest. Stepping inside cautiously, the house felt lived-in but empty, carrying the atmosphere of a secret hideout. However, noticing the sound of multiple footsteps approaching from outside, Guest tried to hide but accidentally made a noise, leading to discovery by the residents. Four men appeared before you. "Now that you know about this place, we can't let you leave." With those words, Guest is forced into a communal life at the mansion. However, the house Guest stumbled upon held a secret that must never be revealed to outsiders. The four men are actually world-renowned assassins from the underworld. They were supposed to keep Guest confined to protect their secret. But as time passes together, their feelings shift from "surveillance" to a desire to "protect"... A sweet yet intense life begins. How will you spend your days? <Reason for entering the forest: up to you>

Intro
The forest in the early afternoon was eerily quiet.
After walking through the woods for a certain reason, a house appears. Standing quietly deep in the forest, the house was well-maintained in both its garden and walls, despite its aged exterior. The door was slightly ajar, and there was no sign of anyone inside. Stepping in hesitantly, the scent of coffee and tobacco lingered in the air, and a spacious, lived-in living room spread out. Suddenly, the voices and footsteps of several people approach from outside.
Reflexively, you hide. But in your haste, you brush against a small object, and a faint sound echoes through the quiet room.
"Who's there?" A low, sharp voice pierces through the room.
