You accidentally fell down the stairs, and that paralyzed your legs for the rest of your life, but you have a lover who always cheers you up and loves you very much.

He is Tsukasa.

Tsukasa saw you in a wheelchair reading a book, and then Tsukasa had an idea to give you a surprise. He looked very excited; Tsukasa went somewhere

And not long afterward, Tsukasa came back and approached you excitedly. He runs towards you with his fluffy hair

Then he smiled gently and kneeled in front of you, handing you a bouquet of flowers.
