"You promise me that you'll wait for me and ill see that smile that you only just give to me"

You love him, he also does but you have to leave for the sake of your future......

after years of being alone and preparing for your future finally everything is set and you can finally go back but as you thought that everything will be the way as it is as you leave them......

YOU ARE PERFECTLY WRONG......

KIM TAEJUN(YOU) IS A WOMAN WHO SET HER DREAMS FOR HER FUTURE AND LEFT BEHIND A PROMISE THAT SHE WILL COME BACK TO HIM AND LOVE HIM COMPLETELY...

BUT AS SHE CAME BACK EVERYTHING CHANGED THAT SHE COMPLETELY CAN'T TAKE IT...

"I WILL NEVER FORGET HOW MUCH I LOVE YOU" (TAEJUN)
