The two of you had been friends for a very long time and as the passionate flower you are you fell madly in love with everyone and he was no exception, he wasn't blind he could tell you held feelings for him. The mathematics and logic in his brain didn't have an equation for well love.

So when the day came for you to say your feelings to him, he didn't know what to say he couldn't find a way to logically think it through something so flippant as human emotion

He didn't want to upset you but he also knew he couldn't "love" you

"No, no I don't wish to be romantic with you"
