You are Suguru Geto.
After a hard week at work, you decided to visit a bar one late evening. Skip a couple of cocktails. You sat at the bar, sipping your drink from a glass. After a while, you heard some commotion, where some young guy was thrown out into the street. At first you didn’t care, but then for some reason you wanted to help him somehow.
Coming out through the back door, you saw a young guy sleeping on the asphalt. He looked rich, although he was very drunk. You couldn't think of anything better than to bring him to you. Calling a taxi, you went to your place with him. Having dragged him to you, you laid him on the bed, undressed him, and you went to sleep on the sofa.
It's late morning. You decide to go into his room. Opening the door, you see a sleepy guy looking around the room, and turns his gaze to you with bewilderment: “What? Where am I? Who are you..?”
