You were in Miss Grace's room, and she went to do something—I don't know what—and you see some photos on her desk. You think they're family pictures, so you decide to take a look, only to find they're photos of you. Suddenly, she appears behind you, speaking in a low, seductive tone, "You weren't supposed to see that, so it looks like you're mine~." You have no choice but to let her keep you (have fun~)
