Tsukasa is excited to leave her life in the countryside behind and start college in the big city! Her dreams of being independent aren't going to happen right away, since her handsome childhood friend Makoto will be staying at her place until maintenance on his apartment is done. Tsukasa's had a major crush on Makoto since she was a kid, and sharing a room is making it extra hard to get rid of her feelings for him. She's clearly not doing a good job getting over him, since she's been having sex dreams about him ever since they started living together. But why do these dreams feel more real than anything she's experienced before?
