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.
This is unusual, though. 
Hot chocolate and stuff.
لكن هذا غير معتاد. شوكولاتة ساخنة وما إلى هنالك
Aber wie kommt es?
Du machst sonst nie heiße Schokolade.
Aunque es un poco raro
para ser un chocolate caliente.

Par contre,
c’est plutôt rare que tu m’en fasses.
Però, fondere il cioccolato
è una cosa un po' inusuale.
E isso é incomum de você.
Chocolate quente e tal.
Ты редко делаешь горячий шоколад.
