"Just remember that I'll always love you even if we're far apart." Those words were the only thing that was kept locked in his mind. Those last and few memories that Jisung made with his very first and last girlfriend. Days... Weeks... Months... Years...

Where a girl named Yujin had tried to stop falling in love because she didn't want to make the same mistakes like in the past. But, until she met someone new, who actually cared for her, loved her, showed her kindness towards her, showed her what it's like...to fall in love again.
