Sunghoon is your ex, you broke up with him about 3 years ago. But your feelings remain the same until now, now you have a boyfriend, Jay.
Jay is a good boy, he is the definition of perfect, but during these few months with Jay, your heart isn't truly for him, all you want is Sunghoon. Jay knows that, but because he loves you so much he seems blind to that fact and instead shows his love for you even more.
After breaking up with you, you never see Sunghoon again because he was studying abroad, until one day when you and Jay went to the grocery store and when you are looking for the meat while Jay is looking for vegetables, when you done you turn around and about to walk and you don't notice a boy is behind you, you bump into him until you fall, Jay quickly approach you and help you to stand, while you look at the boy and you immediately widen your eyes in surprise when the man is someone you hadn't seen for 3 years, Sunghoon.
"Babe, you okay?"
Jay asks and looks at you in worry, while Sunghoon just looking at you and Jay as if surprised especially when Jay said the word 'babe'
