Perfect world 1
"Tsugumi Kawana (26 years old) reunites with her first crush from high school, Itsuki Ayukawa, at a get-together with an architecture firm and the interior design company she works at. He sends her heart aflutter, until she realizes he's now disabled, and in a wheelchair. At first she feels she couldn't date a guy in a wheelchair, but then her feelings begin to change..."--
