Kaoru Terasaki is an MMORPG fan finally meeting a longtime in-game friend face to face. Because his own character is female, he worries his friend will be let down to find out he is a guy. The surprise is on him: his friend turns out to be Nanami Ousaka, a cute girl who has been using a male avatar. The reveal shocks them both, Nanami most of all, since she has already told her eager mother and overprotective father that a female friend is coming to visit. Her dad will not let boys anywhere near his daughter, so Nanami proposes a way out: Kaoru will cross-dress as a girl. Their friendship began with lies on both sides, and this strange meetup starts an unusual bond in a romantic comedy about whether the two will stay just friends.
