I've been trying to find this story for a while now. It's a Gravitation story with Main Characters Shuichi and Yuki. From what I can remember.
Shuichi gets hurt when the elevator in their apartment crashes to the basement. His back gets damaged but not paralyzed. At some point they move from the apartment to a house to make it easier on Shuichi while he is in a wheelchair recovering. Shuichi pisses off Yuki and Yuki wheels him outside the house so he can get some work done. A storm comes through and Yuki remembers Shuichi is still outside. Shuichi ends up sick and upset with Yuki for neglecting him.
That's all I can remember from the story. If it sounds familar and you can find the name. I would greatly appreciate it.
