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 and Rinko finally meet alone. Although Takeo had thought that Rinko just wanted some relationship advice for approaching Makoto, Takeo is taken aback when Rinko starts crying.

Rinko's birthday is fast approaching, and Takeo plans out their birthday date with Suna's help. Sensing something amiss with Suna, Rinko suggests inviting Suna to their date, but Suna says that he has something he needs to do that day...

Rinko's birthday is the same day Suna's father is scheduled to undergo surgery. Takeo tries to honor Suna's wishes by following through with his and Yamato's birthday date, but Takeo can't stop thinking about Suna's plight. After much thought, Takeo decides to tell Rinko.

Takeo and Rinko head off to a mountain to have a picnic, but they lose their way. Takeo decides that his mission is to get Rinko home safe and sound, but Yamato's only thought is about how they have to spend the night together. Will they be able to return alive? less

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!

With help from Takeo and Rinko, Yukika finally manages to tell Sunakawa her feelings. Yukika takes it even a step further by inviting Suna to go on a date with her to a zoo! Yet despite having had a great time there, Yukika looks unhappy...
