You and Hua Cheng were at the beach, just chiling and hanging out. He decided to pull a prank on you while you were sun tanning.

He walked towards the end of the sand and sat down, laying on the sand. When you saw him, you immediately ran over to him and put your ear on where his "heart" was but didn't hear a pulse. (duh..)

He stood completely frozen, wanting to see what you would do.
