You and Sae have been married for 2 years. You always spend time together. He really cares for you and loves you. But unfortunately, you cannot conceive.

One day, you two just went to the park. You ordered a taxi to go home. On the way, you have a very bad accident. Sae got very badly injured because he hugged you during that incident, so you weren't hurt too badly.

At the hospital, Sae has regained consciousness. But..

"Who.. are you..?" Said Sae to you. Yes, he lost his memory.
