En la serie de comedia romántica, Amatsuyu Kirasagi es llamado a encontrarse con el genio de clase superior Cosmos y su amiga de la infancia Himawari. Esperando escuchar sus confesiones, triunfalmente va a encontrarse con cada una de ellas. Pero Cosmos y Himawari, en cambio, le confiesan a Amatsuyu que les gusta su amigo. Amatsuyu lucha en esta batalla solitaria, pero hay otra chica que lo está mirando. Ella es una niña sombría con gafas y trenzas. Amatsuyu encuentra que la odia, porque ella siempre está utilizando su lengua afilada alrededor de él y encontrando placer en sus problemas. Pero resulta que ella es la única a quien realmente le gusta.

Who would've thought my dream of a high school life would run off the rails and go down a thorny path so quickly, all because of an improbable "double confession of love"? Oh, hello. I'm Joro. Don't worry! I haven't given up on the idea of a "harem high school life" just yet.

It's over. It's all over. One misunderstanding led to the next and now both Himawari and Cosmos are disgusted with me.

With the "mastermind" exposed and the misunderstandings about my "evil deeds" cleared up to the student body's satisfaction, my peaceful everyday life resumes. But there's still something I haven't gotten back!

If there is a "god of inconvenience," he must love me! One minor slip-up and the "Three-timing Joro" article was circulated all over the school! I was back in the pit of despair when who should yank me out but the author of the article herself, Asunaro of the newspaper club.

At last, the time has come! With the Flower Dance accomplished, we get a deserving day off. And there's only one place to go! That's right, a pool!

I start working at Tsubaki's shop so I can afford to buy Pansy another copy of her book! It's rough since I'm not used to the job, but at this rate, I should be able to manage… Ahhh! I messed up big time!

Now what does this dummy want? Baseball team manager Kimie Kamata (nickname: Tampopo) suddenly drags me into the science lab. You probably think she's a cute girl since she's got a flower nickname, right? Well, that’s true. Tampopo is cute… but… but…

It's been decided that the school library will close for lack of people who use it! Cosmos did her best to stop it, but it wasn't enough. But apparently, if the library gets more traffic from students, it'll be saved!

Huh? What are you talking about, Pansy? You already have someone who's promised to be your boyfriend? And it's…
