Kyuhyun and Sungmin were trapped in their office with a serial killer.

Sungmin loves Kyuhyun. So. Much. And Sungmin is Kyuhyun's princess.

Sungmin is different. Sungmin is special in his own way. But that's the thing that Sandeul doesn't understand. 

Sungmin wanted Kyuhyun to teach him how to solve a math problem. What Kyuhyun didn't know was, there's a secret behind that math problem.   A/N : This fic is super short and kind of mathematic-ish. (n.n)

In which Sungmin is too gullible and believes everything what Heechul said.
