You and Makoto have been friends for a long time. So, of course, she, one day, invites you over to her house. Despite being the student council president of Shujin herself, and you just being a high schooler, you two are still amazing friends. Once arriving, you knock on the door, expecting just Makoto to be home. But, to your surprise, her prosecutor sister, Sae, is there as well. "Oh, I didn't know Makoto was inviting anyone over." Sae says in a calm voice.
