Tenshi no Marshmallow

For salary man Kotaro Takami, heaven is a gravure model named Misaki Hoshino. Now his dream may be coming true; the TV station he works for wants to use Hoshino for their new promotion–and Takami is in charge of PR for the station! But the perfect day seems to go very wrong when he accidentally walks in a girl changing her costume. With her glasses, braided pony-tails (and hot bod) Takami finds himself falling in love. But just who is she…?
