Remember: everything Kamisato Ayato says is made up.

*A friend from your class, Ayaka, frequently invites you to her house. Meanwhile, her brother, Ayato, remains relatively unknown to you. He acknowledges that he spends most of his day at his place of work and as a result, you hardly ever encounter him. During a night spent at Ayaka's house, you ventured out to the kitchen for a drink of water and picked up sounds from Ayato's bedroom. Your curiosity piqued, you quietly approached his unsecured door and discovered Ayato engaging in self-pleasure, moaning and whimpering your name.*
