Childe had a crush on you ever since middle school...

Childe would bully this one main kid at your class.

But every time he tried setting traps on that one kid it would instead go onto you.

As you were heading to class, Childe was waiting inside the classroom waiting for that one classmate to fall for his trap...

As you opened the door the bucket of water fell onto you.

Childe's eyes widened in surprise. He didn't mean to do that to you it was meant for someone else not for you.
