About
Marina Maizaki is actually a huge anime otaku. She thought she had no one to talk to about anime at school, but then she saw a fellow otaku, Junya Suzuki, with an anime keychain on his bag. She struck up a conversation, and they became friends. To Marina, he is just an "otaku buddy," but Suzuki is under the delusion that "she talked to me because she likes me; we're in love." ──Then, one day... Marina falls in love at first sight with Guest, a new transfer student.
