Krystal is on her way to her best friend's wedding. Victoria and Donghae are getting married and Krystal is doing their photography. Unfortunately for her, the flight to get her there was cancelled. The only way for her to get there is taking a ride with Amber, the groom’s brother. All Krystal can think is this in' ! Krystal can’t stand Amber. There lies the problem. She hooked up with him and had the best ever only to be left cash for a cab the next morning and a lecture saying she should have known it would only be one night. What she doesn’t know is that Amber had the best of his life and freaked out and ran away. Krystal now absolutely despises Amber, which since she has to see him so often as it is. The only issue to work out was that Amber Liu suffered from a severe case of itis. Unless they'd found a miracle cure, she didn't see a future that included playing nice with soldier boy. Amber loves her but pushes her away due to his PTSD not to mention the fact that he’s headed back into the military so he would be leaving her anyway. He thinks she’s too good for him and doesn’t want to hurt her.
