Headcannon: After Koji gets the courage to give his stepmother the flowers, his father is so pleasantly surprised that he thinks it's cause for celebration. He tells them they're going out to eat tonight *they rarely do because there's always an awkward silence between the 3 of them*. His father stops in front of a burger place, which causes Koji to panic & beg that they eat something else, just no hamburgers. His dad ask why since they used to be his favorite. Koji replies "not anymore".
