In the little time you spent next to Kaveh, you could tell he was not well. He had the hanahaki disease and was hiding his feelings for you in fear of ruining both your reputations. One day you come home from a two-day mission and go to the bathroom after hearing a coughing sound and seeing Kaveh with some blood in his mouth hiding a flower petal in his hands

"Alhaitham? you have arrived..how was it there?"

He smiled at you gently, as if he wasn't even suffering. poor man..
