Hello Hello, I'm hoping to a find a similar romance supernatural manga, where one character as a supernatural power that they find effects someone else' and are thus forced into a partnership of sorts. In the case of Barairo My Honey Koume can tame the Boss's tiger. Thus linking them together, much as he hates to admit it or bring her into it he needs her in his life to help control that power. I'd like to find something where a similar partnership is created, preferably if that partnership evolves into romance. (In a way Legal Drug also fits (not that there's any romance but there's enough suggestion to make me smile) but I can't think of any other examples at the moment[/m])

Midnight Secretary (by the same author)
Hitsuji no Uta
Nanatsuiro Drops (from what I've seen in the anime)
Kanata Kara
Midori no Hibi

Gotta love forced partnerships based on the situation at hand.
