Mahiru's father heard from her mother that she received a gift on White Day from a boy, but Mahiru tried to hide this by saying she received the gift from a girl. With her father coming to Wagnaria to confirm whether this is true, Inami asks Sota to cross-dress for the day to fool her father. While he initially vehemently refuses, the other employees get him to chance his mind and he goes along with it, going under the identity of Kotori. When Mahiru's father finally arrives, Sota starts a conversation with him, and finds out that he actually indoctrinated Mahiru over a period of ten years using films, TV and books to make her fear men, as well as placing a weight in her bag to make her muscles stronger. Sota angrily lectures him about his parentage and tells him to go home and later apologize to his daughter. Mahiru realizes she is in love with Sota after watching this performance.
