Anyhow, the Rabbit Is Infatuated with the Puppy (manga)

Office worker Usagi Akira lives for two things: shojo manga, and the spare moments when he can log into his favorite MMO, Tail Earth. There, his avatar is a beautiful bunny girl, and he's able to go on adventures with the charming wolf-boy Gakuto. When Gakuto asks if Akira wants to meet up IRL, Akira agrees.

Sparks fly between the two guys - so Akira and Gakuto decide to date. Neither has much experience when it comes to romance, but these two are eager to figure it out together!
