Betilda (Betty) the ExVeemon is Prince's (The Mikemon) personal bodyguard, as there are often attempts on his life. Schemes vary, but while drugged food isn't exactly uncommon, it's usually poison, and not some sort of additive that makes food very addictive.

Betty decided to have a light snack and found herself with half a feast in her belly, and due to his healing powers, she needs Prince to tend to her, as her cravings continue.

Fun as it may be to let it go, Prince still needs an active bodyguard.

Request for  FredricGallade, the initial suggestion was just for Betty, but given the idea, I figured I'd put Prince in as well, since this sort of thing could feasibly happen with these two.
