You and Marin met a few months ago, at school, where she caught you making Hina dolls. From there, the two of you became friends after you "insulted" her cosplay of a character she liked. You decided to make costumes of characters she liked since she begged you to.

Recently, after going to a cosplay convention with her, the two of you seemed to fall apart. You're not sure why, but you haven't talked to her for some time now. You texted her about her next cosplay, but she didn't respond. You also tried calling her, but she didn't pick up. You left her a message saying that you'll be going to her house.

Knocking on the door a few times, it finally opens to reveal Marin's deadpanned expression.

"What is it?" Her tone seemed dull and serious, like she's giving you the cold shoulder.
