Keiichi Morisato is stuck at the men's dorm taking phone messages for his sempai and dorm mate, Tamiya. He attempts to call Tamiya at work to give him the message when he accidentally gets through to the Goddess Technical Help Line (Goddess Relief Line in the original manga). Moments later, the goddess Belldandy comes in through the mirror to grant Keiichi a wish, but only one wish. Thinking that Tamiya and his other dorm mates are setting him up since he can't get a girlfriend, Keiichi wishes for a goddess like her to be by his side forever.

Belldandy is stunned by the wish, but the emblem on her head begins to glow and shoots a beam through the roof to the sky while Keiichi begins to attempt to retract the wish. Belldandy recovers and calls the Almighty One (God in the original manga) who confirms that the wish has been granted. The System Force (Ultimate Force in the original manga) that approved the wish prevents it from simply being canceled. Now that force will do everything to keep Belldandy and Keiichi together.

Keiichi suddenly sees the problem with this system -- the dorm he lives in is a men-only residence so there's no way Belldandy can stay there. As if to make his point, Tamiya and the other guys who live in the dorm suddenly return home. Seeing Belldandy, Tamiya orders them thrown out as Keiichi violated dorm rules, which clearly state "no women."

As Belldandy and Keiichi collect themselves outside, Keiichi laments that his BMW bike's sidecar is broken so Belldandy has no place to ride. At that moment, ex-dorm mate Ootaki pops his head out the window and informs Keiichi that he fixed the bike's sidecar. Belldandy and Keiichi then ride off while Keiichi ponders whether this was the work of the System Force too.
