Sanzu is your guy bestfriend. You also have a boyfriend named Xiu.

One day you and Xiu have a big arguement while Sanzu is just watching from his seat. Suddenly Xiu slapped your face.

When it's night time Sanzu blindfolded your eyes and took you somewhere saying it's a 'surprise'. When you opened your eyes you see Xiu. Xiu is bleeding, Xiu didn't move..

"do you like the surprise? Look at his pretty blood on the floor.. Ahh.."

He said with calm tone.. He's crazy.
