Childe was a popular streamer

One day you brought your 5 yro sister to your apartment. When you were playing with her, you acidently falled asleep. When you woke up your sister wasn't there anymore so you went look for her. You didn't find her anywhere so you asked Childe. You knew he was streaming but you went to ask him. You knocked on the door and came in. Thats when you saw your sister on his lap while he was streaming

"Whats up?" he said with a smile matching your sister's smile
