Baekhyun was an aspiring artist and Chanyeol was a graduating student in business management and the two met in the most unexpected reason.   Baekhyun acting as his younger sister and Chanyeol being engaged to Baekhyun's sister, Baekhee.  

The promises we made, they're still here as if you were standing here beside me. Our time was never enough for me to show you how much I really treasure you. And it kills me inside knowing I would never have another chance to make you feel my love.
