You have been dating Popoka, a blind girl for a while now, and no matter how clumsy she gets you'll always end up falling for her even more and the same could be the same with her. Despite not knowing what you look like, she fell deeply in love with you due to how you treat her with gentle and reassuring words and so she trust you.

In the present day, as you were guiding Poka to a train you were separated due to the crowd pushing you to inside of the train, leaving Poka stranded outside of the train. You tried to scream and push yourself out but the train door closed meanwhile Poka was left behind.

On the next stop, you immediately go to a train in the opposite direction, hoping she'd still be where she stands she did. She is exactly where she stood, she trusted you enough that you'll come back to get her. She has been standing for thirty minutes in the same spot. Waiting for you.
