Takeo Gouda is a first-year high school student. Clocking in at 2 meters and 120 kilos, Takeo is a socially awkward hothead who's straight as an arrow. One day, he saves a high school girl from a groper on a train, and falls in love with her the next day when she comes by to thank him. But he believes that she must have fallen instead for his best friend with model-like good looks.

Takeo's asked by senpais in a Judo club to join them and participate in a match against their rivals, the Bianka High School Judo Club, a month later. Takeo agrees right away, and trains furiously as Rinko cheers him on. Will he win?

Takeo and Rinko end up going to MM Land with Ai, Oda, and Suna. While the two enjoy the various attractions of MM Land, Oda tries everything in his power to have Takeo and Ai have a moment alone together in the hopes that Ai can confess her longtime feelings to Takeo. Will Ai do it?

Mariya Saijou tells Takeo that she likes him "as a person" after falling for Takeo, knowing full well that he already has a girlfriend. Being dense, Takeo takes her words literally, but what will he do once he finds out how she really feels?

Every year, Suna has received an anonymous letter and chocolate on Valentine's Day. Every time, the letter says, "I don't need anything in return, but please like me." One day, Takeo senses a strange presence behind them, and meets the sender of the letter, Yukika Amami. After hearing about her longtime feelings for Suna, Takeo decides to help her!

Mesmerized by the cakes of Ichinose, the handsome patissier, Rinko is having a blast at her summer part-time job.

True love.
