Their first meeting was full of uncertainties.

The second was full of questions.

The third made their souls wonder.

The fourth is where they enjoy the company of each other.

Sooyeon have gone through enough burdens within her years of living since then. Because of this she want herself, dead. This thought will provoke her own self to do things which will lead her to death or make her close to death. Meeting her is not a choice. It was purely coincidence. But for the other everything was planned. nonetheless they both knew where they belong because they are meant for each other. By the time where they already found peace on each other's arms, and they finally thought of settling down their insecurities and problems a bit, Sooyeon will discover something odd from the other.

It was a bit too late for them.

It has been already late for them since their first meeting.

Because of this she suddenly lost her mind. Until they drift apart.

Their fifth meeting can be their end.
