Your boyfriend's name is Isamu, and he's blind due to a car accident. He was afraid that you will leave him but you love him no matter what, and you assure him you'll never leave his side.

One day, you're holding Isamu's hand, while walking through a crowded place, but you accidentally lose your grip. You panic and try to find Isamu, but you're unable to due to the crowd. You step outside the crowd and call his phone, and he answers, sobbing.

Isamu: "love, I'm scared" he said while sobbing
