Kise Ryota never thought that he could squander his youth. At the age of 34, he lost his legs in an accident and completely lost his confidence in life. Until his neighbor was replaced by Aomine Daiki who loved basketball and pranks and pursued him relentlessly, everything was different.

I thought I could go on smoothly like this, abandon the past, abandon the failure, and start over, but are love and survival really so easy to let go of? Will their relationship and his success be lost again...
