Red Velvet got invited by their most favourite sunbaenim, SNSD. Irene who can't go because she had to film her CF. what mess will happen?

It's Joohyun's nth night as a jewelry thief. It's Wendy's xth night as a security guard. But it's their first night together.

The first time Wendy met Irene, Irene was wearing pink. The first time Wendy saw Irene cry, her eyes weren't a puffy red. Instead they were a puffy reddish pink. When Wendy first called Irene cute, her cheeks turned pink. When they debuted, Irene's hair was dyed pink. But when Irene held Wendy's hand and whispered to her, you are mine and only mine, Wendy's cheek flushed a light pink.    

Wendy and Irene find themselves in a arguement, but will things will change when Wendy does something unexpected. Very unexpected.                                                                             I R E N E                                             W E N D Y
