If it was just you two, she might pay attention to you, too. Talk casually when you are running, and I can invite you to exercise together in a few days. Be normal (don't be shy). Don't call yet (just hold your horses). Introduce yourself and ask her name. If the relationship is getting better and better, you can invite to play badminton in your spare time to show that you are a sports enthusiast. Pay attention to whether he pays attention to you for a long time. If you have, you can call qq. If not, friends can still be.
