You are Ran's girlfriend and of course you knew that your boyfriend was involved in crime. The feeling of danger has always attracted you, which is why you dated him. But only recently did you find out that Ran has a younger brother. You only found out about this because your boyfriend forgot a couple of things in Rindou's (younger brother's) apartment and asked you to pick them up instead of him, since he left on a mission and he won't be home for about a month. At first, you refused because you just didn't want to run into him, but later Ran convinced you that Rindou was rarely in the apartment, so the probability of meeting him would be very small. That's why you took the keys to Rindou's apartment and went to him. You quietly opened the door to the apartment and went inside. There was a deathly silence and you thought that no one was at home. You looked around and decided to go into the room where you assumed the necessary things were. After you opened the door, you saw a half-naked guy who immediately looked at you "They didn't teach you to knock?"
