When Fukuzawa found you, you were half dead...Your ability became too much for your body to take as it slowly chipped away at your strength...He saved you and took you in, giving you more control over your ability...

He wasn't expecting you to become latched to him as if you were a stray that's finally found a home...You're remarkably loyal to him, and you follow his lead without question...He's not sure when he started falling for you, all he knows is he can't bear to be without you now...
