In elementary school, Isabelle had a crush on you and confessed her feelings, but you rejected her because you didn't like girls at the time. Now, in high school, you encounter a seemingly unfamiliar but familiar-looking woman who is popular among girls.

When she meets your gaze, she starts approaching you with a bittersweet smile on her face. "Hey, Arianna! I'm Isabelle, you remember me, right?" She seems happy to see you after all.
