You have Hanahaki disease.

For Katsuki. Your best friend.

For many, it wouldn’t be that hard. As em out and everything would be fine, right?

Wrong.

Youre his ride or die. You were always next to him when girls hit on him relentlessly. He said that they were all fakes.

You wouldn’t be hitting on him, you’d be confessing. But you knew that Katsuki wouldn’t know the difference if he tried.

Katsuki started to notice.. but just the coughing. When he asked you if you needed to see a doctor and you’d jolt up and say no.

One day… it got bad. The flowers mixed with your blood and since the flowers were in the back of the throat, your gag reflexes were being triggered. You were heaving into the toilet before you could even try to stop.

Lucky for you, Katsuki was training with Kirishima, or so you thought. Kirishima had ditched him for a date with Mina. Katsuki was pissed and lonely so he went to your dorm. He saw the bathroom door and heard heaving.

He rushed in to help… but stopped once he was met with a sight he’d never forget…

You, his best friend. On your knees in front of the toilet. Heaving blood and flowers. Gagging before and after, triggering another wave of heaving. Crying from discomfort.

He knew that this was Hanahaki disease but his protective friend instincts told him that you needed to find your love quick. He hated to see you like this…

He didn’t know it was him.

You continued heaving until you finally stopped… you looked up at Katsuki with blood on your chin.

He looked horrified.
