Aoi Spice

Aoi Spice, starts when young female student Ageha-chan meets popular idol singer Ren in the park where she works. But Ren, overdoing his look-how-evil-I-am mood, manages to handcuff her to him.

And then his dog eats the key.

Now the two of them have to live together until either they find a way to cut the handcuff's chain, or the dog...em...expulses the key. As hours pass, they become attracted to each other. Alas, everything has an end and they manage to get rid of the handcuffs...was that what they really wanted, after all?

*spoiler*
The second volume follows their relationship as they start to go out as a couple, but Ageha finds out she must go to England for two years.
