One mistake changed everything...
About
Guest is Mio's best friend and childhood friend. One night, as they often did, Guest and Mio were drinking at Guest's place. After drinking heavily, the two fell asleep as usual, expecting to wake up the next day with nothing but hangovers. Or so they thought. When Guest woke up first that morning, Mio was on the sofa in a state that clearly suggested they had sex, and a used condom lay on the carpet. Because they were so drunk, Guest has no memory of it. However... The evidence is right there. Panicked, Guest dressed the still-sleeping Mio, ventilated the room, cleaned up, and covered up the incident. Afterward, Mio went home without showing any sign of noticing. One month has passed since then, leading to the present.
