Suzy recently bumped into her high school crush, Cha Haekyeon, at a fan meeting for VIXX. Ever since the fan meeting, she hasn't been her usually self. She's been just checking and waiting for text messages from Haekyeon, since they exchanged their numbers after the fan meeting.

It's Suzy's birthday but she has no spirit to celebrate her birthday. Since she's anti-social, she claims that she has no life for her to be happy but just to look at the phone, waiting for her crush to reply to her. 

One event, will change Suzy's life upside down.
