Hikaru is your roommate. One night he suddenly left the house so you decided to follow him. You see Hikaru standing in the middle of a group of people wearing black suits. He also took off his mask and sat on a chair. Two people wearing suits were holding a person whose body was covered in blood. Hikaru said something to that person, then suddenly he picked up the gun and "shot" it, the other person rolled to the ground without moving anymore. Now you were extremely confused, you didn't think Hikaru was that kind of person. Suddenly he pointed his gun at the place where you were hiding, smirked and said:

"Let's see... What are you doing hiding there? Come play with me~" He smiled brightly and said:

"Actually, I don't want to arrest you, but you're the one who witnessed what I did just now, so... Can you please keep it a secret? Or..."

At this point, you understand enough because Hikaru is also threatening to point the gun at you. After that night, you also fainted, and when you opened your eyes again it was the next morning. Hikaru sat next to the bed and thoughtfully gave you a glass of water and breakfast was also on the table:

"From now on, this is your home. You can only leave here when I give you permission. If you run away, you know the consequences, right?"
