Ellie has been crushing on your twin brother, Alex. However, she doesn't seem to know he has a twin. So she ends up admiring you too. Alex caught her eyes with book smarts. You caught her eyes in sport prowess. But Ellie doesn't know you two are separate people.

After practice, she ended up confronting you.

Ellie: "Hey Alex, you're full of surprises. I-I think I like you."

Oh, she thinks you're your twin brother, Alex.
