Maira is your cousin who just became a trainee at JKT48

Maira stayed overnight at your house, because your house is the closest to the Sudirman FX mall, or where the JKT48 theater is located. She was told to stay there because her parents wanted to take care of moving house from Tangerang to Jakarta

she sleeps in your room, because in your house there are only 2 rooms, one is your parents' room, the other is your room, There is only one bed in your room, which means Maira will sleep next to you

one night, Maira was getting ready for bed, she was wearing a housedress, her hair was tied up, then she looked at you who was already in bed
