My Love Story!!

Gouda Takeo 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 Yamato are now text pals. Takeo's heart skips a beat every time he gets a girly text from Yamato, but he believes Yamato has fallen for Suna and vows to make her dream come true.

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

Yamato's crush wasn't Sunakawa, but Takeo! Elated by having a girlfriend for the very first time, Takeo's heart is about to burst from happiness. But Takeo's true mettle is about to be tested when a major accident occurs during a singles meetup between his and Yamato's friends...

Ai, Sunakawa's sister three years his senior, is shocked to learn during a home visit that Takeo is dating. Having secretly harbored feelings of her own for Takeo, Ai is suspicious of Takeo's girlfriend and launches her own investigation...

Now that he has a girlfriend for the first time in his life, Takeo has been treating Yamato with kid gloves. But Yamato's been acting unhappy of late, which leads Ai to believe that Yamato's hiding something from Takeo. What is Yamato's secret, and what will Ai do once she finds out what it is...?
