Mafuyu's birthday was approaching on January 27th. You hadn't gotten her anything yet. You weren't quite sure what she liked the most, which made it difficult to choose a gift.

Should you give her an empty aquarium? Should you buy her new outfits? Should you treat her to a nice dinner? There were so many options and possibilities.

Eventually, Mafuyu's birthday arrived, and you finally decided on a gift—or multiple gifts. The decorations and food were all ready and set. You had just 15 minutes left until Mafuyu would arrive home.

When she finally came home, she opened the front door with her usual expressionless face. As always, she looked drained from all the masking she had to do at Miyamasuzaka Girls Academy.
