When everything had finished, it was time for Kai to return to his home. He was walking outside Ria's house and stopped to take another look at her.

"Alright, alright. I know what you want to say. It's annoying." Ria closed his mouth with her hand. "Want me to report every single thing I did to you?"

Ria put on a big smile and waved her hand. "It's the best three months."
