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, Amami Yukika. After hearing about her longtime feelings for Suna, Takeo decides to help her!
Still, every time Valentine's Day comes around,
ومع ذلك كلما حلّ عيد الحب
Aber jedes Jahr am Valentinstag
Pero cada vez que llega San 
Valentín me planteo declararme.
Pero cada vez que llega San 
Valentín me planteo declararme.
À chaque Saint-Valentin, 
j’essaie de faire ma déclaration…
Però, ad ogni San Valentino,
Seja como for, chega o Dia dos Namorados
