On Valentines Day, after the two neighbors eat dinner together as usual, Mahiru gives Amane some hot chocolate. Amane accepts it as a normal Valentines Day gift, but Mahiru seems restless, as if she has something to tell him. When Mahiru rushes home, still unable to say whats 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 doesnt like very sweet things. In return, Amane gives Mahiru a special present on White Day.
