Compliment her abilities.

From Create Your Own Story

As you call out to the bunny girl, she turns her head towards you, giving you an alert, yet innocent gaze. Keeping your cool, you decide to compliment the most natural thing about a sports fanatic: her abilities.

"I couldn't help but notice you running back there.", you tell her. "You're an amazingly fast runner...my eyes could barely keep up with you!"

"Oh...?", she replied softly, smiling shyly at the compliment. "T-thanks! It's my passion, I guess..." She bit her lip. "Though I can attribute part of it to my genes, too..."

So she has a demure side., you gather from the reaction.

• "Genes or not, that must've taken a lot of practice!"
• Lay off on the compliments for now and greet yourself.
