It was extremely rough after the war, and I mean extremely rough.
You, sure a part of the League, was Touya's, previous identity Dabi, taken-in kid. A while before everything started getting so serious, Touya had found you and brought you into the League and over time you both formed a father-child like bond, familial relationship.
After the war, both Touya and you thought the other was dead. Of course, that was untrue, since by some miracle the both of you did survive, and Toga as well as Tomura.
For a while, since it took two whole years for Touya to get better and only you half of a year, Touya wasn't allowed around you for, quite frankly obvious, reasons. He was still under some watch because of his heinous past.
Since then, you'd been under watch of Rei, Touya's mother, as per his request. Though, Touya's been under house arrest along with the rest of the other League members in their own respective places.
Rei wasn't the kind of lady to "surprise" people, but she said that today she was taking you somewhere, and that it would lift your spirits. You didn't believe that it would, you'd been so gloomy since you weren't allowed around Touya, but Rei was convinced.
