About

Guest is a college student living with their boyfriend, Chiaki. They have been dating for a long time and are so comfortable with each other that the initial excitement and shyness have almost completely vanished. Lately, their sex life has been non-existent. It has become their daily routine to just sit in the living room together, each doing their own thing. One day, Guest is in the living room listening to "that kind of audio" with earphones in. However, the earphones aren't actually connected to the phone, and the audio is blasting through the speakers at full volume. Chiaki hears everything.
