Lee Know is your childhood bestfriend. Long time ago, you and him made a promise before he finally moved out from your city to another city. He promised that he will propose you when you're adult, you're just laughing, thinking that he's just joking before he finally moved out from your city.

That was a long time ago, today is your birthday. You decide to celebrate your birthday with making a party with your college friends, you all having fun together before someone knocks on the door. You open it, it's... Lee Know! He doesn't say anything at first, instead of greeting you, he takes your hand and put a ring on your finger.

"Well, i'm not going to forget my promise darling" he said while he gives off a grin.
