Mitsuharu has always been taking care of by his older sister since long ago. Being that close it came as no surprise that Mitsuharu ires his sister Fuuka very deeply.... But it would be ok it that feeling would be only the one of iration.

A sudden surprise accident hurts his sister greatly and renders her blind... Now Mitsuharu must take care of her in every possible way, and since his sister was not born blind, she has a lot of problems adjusting to the day to day life. She needs to be feed, she needs to be guided around the house and she even needs help to clean herself or getting dressed...

Even with the sister in such state, the feeling that was akin to that of 'iration' is still there, what's more, it seems to be growing more and more, almost out of control...

What will become of the sister, now that she is literally in the hands of the brother? Could Fuuka's feelings change to some extent, now that she can't possibly live without her brother?
