It's a chance encounter for the unwilling Oh Sehun and the ever exuberant Lu Han. Both are alone in this Christmas Eve. Both are strangers to each other and when the other is coming home, the other is avoiding what could have been his home. Both are struggling with reality; where one is on the verge of losing and the other is still learning to let go. 

He doesn't blame Minseok for leaving him on his own devices that day, but Zitao wonders if the night he first met Sehun is a moment he would want to never happen.

Sehun's time is ticking. Zitao holds the stopwatch.

The new addition in school weekly newspaper is designed to help the students with their problems without creating a new one... Or so the columnists hope.    

Today is second of May and Oh Sehun is 40 years old.  

Minseok doesn't have to consider Lu Han's feelings. It's not like he can touch him anymore.

He doesn't know what a forgotten, simple habit can do to one's fate.
