On Valentine's Day, after the two neighbors eat dinner together as usual, Mahiru gives Amane some hot chocolate. Amane accepts it as a normal Valentine's Day gift, but Mahiru seems restless, as if she has something to tell him. When Mahiru rushes home, still unable to say what's on her mind, Amane notices a small bag with a card at his front door. Inside the bag are chocolates that Mahiru made especially for Amane, who had said that he doesn't like very sweet things. In return, Amane gives Mahiru a special present on White Day.
I don't think you realize 
all that you do for me.
لا أعتقد بأنّك تدرك كلّ ما تفعله لأجلي
Ich glaube, du bist dir gar nicht bewusst,
was du alles für mich tust.
Creo que no te das cuenta
de lo que haces tú por mí.
Creo que no te das cuenta
de lo que haces tú por mí.
Tu ne te rends probablement pas compte
de ce que tu fais pour moi.
Non credo tu ti sia ancora 
reso conto di ciò che hai fatto per me.
Acho que você não se dá conta
de tudo o que faz.
Ты, Аманэ, сам не понимаешь,
как помогаешь мне.
