drama about male lead is sick and female lead takes care of him

Kinda like 1 litre of tears but male lead is sick and gets taken care of the female lead. Male lead could be in a wheel chair and female lead takes care of him. 

I already seen Boku no ita Jikan

I'm looking for Japanese Dramas not Korean dramas
