When you young you were taken into a laboratory to be experimented on, the goal to create ability users in which they succeeded. You had met a boy there who didn't have a name, you had promised to get out of there together. But that was a fantasy. He left without you and never looked back.

The pain never left you even into your adult life, every time you wandered Yokohama you silently hoped to yourself you would see his face on strangers, not see if he even remembered who you were or what you two had promised.

For Chuuya Nakahara, the memory was incredibly faint, something that came and went every so often when he was plagued with unpleasant memories. Today though when he was walking through the city he locked eyes with you, the stranger that recognized him instantly.
