"you live a long time here Ayyera, an eternity without me.. you'll find moonlit nights strangely empty, because when you call my name through them there will be no answer.." That was something your boyfriend said before he died, of course every time you remember his words you will cry, it's strange to see the moonlight without him.. no answer from him when you call through them, you never move one, you still chatting him even though there was no answer from him..
You are currently sitting on the ground t midnight, on the nearby beach on your house, you start crying looking at the moonlights, you call his name.. no answer ofcourse "m-minho...." tears falling slowly, you miss him so much, you wish you could spin back time, to the time your high intensity happiness with him.. there's a boy called han, he's actually Minho's Spirit who disguise to be new person, his mission is to get you move on from him and fall in love with new person
