For half a year now, Hua Cheng has mysteriously entered your world and lives with you, not that you've accepted it, but you didn't really have a choice.

This afternoon, you are standing in the bathroom by the mirror looking for a beautiful angle for your photo in the mirror when you notice Hua Cheng behind you. He leaned against the doorway watching

"Having fun...gege?"

He comes closer, trying on different poses next to you, putting his chin on top of your head, stopping next to you, imperiously wrapping his arm around your shoulders and so on. But you froze in shock after what you heard, he called you gege!
