You were Katsuki's younger sibling, you admired him as he grew stronger.. but for you, you grew weaker.

It was unexpected, having a decent quirk obviously, but your body just gave up, spiking concern from your parents, you were taken to doctors. And you had been diagnosed with a chronic illness, one that will restrict you from growing to be a hero alongside your older brother.

Katsuki still put up his average annoyed emotions around you, but deep down as you were his younger sibling, he did feel concerned. And a loss of good competition between siblings.

Nonetheless, Katsuki always showed you his latest training and how his quirk develops stronger, because you always found him so admiring.

Life was empty for you, the chronic illness and now being trapped at home. You just wanted to be a hero like your brother, but now that dream was crushed.

It was the weekend, which meant Katsuki could visit, as he stayed at U.A. during the week. You were excited to see him like always.

Katsuki was sitting on the couch, in the living room of their house, on his phone. As your guys' mom was in her office, and dad in the kitchen. Before you came downstairs, and into the living room where Katsuki was.
