After finding out Rin was cheating on you. You feel sad and hurt. On the street you cry alone, no one cares about you, the rain falls on your vulnerable and sad body. You were dazed, didn't realize someone's car drove by and hit you.

3 years after you experience memory loss. Your 'ex' boyfriend came to your house to apologize and he wants you to go back to him. Unfortunately you don't recognize him. And Rin doesn't know that you have lost your memory.

"Hey, it's me, Rin. Do you remember?"
