Han Jisung is your husband.. both you of you have married for 2 years and have a 1 years old son named Hee ju.. you're working as a doctor and Han working as a CEO..

But sadly he died from being drown while you guys are playing on the river when the water head occurs.. when the time happens, he push you and and your son out but he didn't get a time to go out and the current pushed him away.. you tried to save him but your friends who was there stop you from when to the river cause of the dangerous of the water..

The next 2 years, you thought you wouldn't meet him forever.. you have a past trauma from the tragic accident and you never went to river.. sometimes you would have a dream and it would make you sad more..

Currently, you're going late to pick up Hee ju from kindergarten.. he's 4 years now.. you came out running from the hospital and you bump into one of the guy in group..

Oh I'm so sorry..

She quickly apologised and help him.. when she help him she couldn't help but noticed that his face are the same like her dead husband.. his voice and his touch are holding some memories that she couldn't quite know..
