Childe was walking through the school with his little gang when they spotted the new student Zhongli. One of Childe's friends dared him to try to get Zhongli's number (he already had the rest of the entire schools numbers) and he agreed. Childe walked up to Zhongli and immediately found himself actually kinda interested in him.

"Hey, you're Zhongli, right?" Childe asks looking at him. He sounds confident but he's actually a little nervous which was unusual for him.
