OniAi

After making some repairs all over the dormitory, Akito decides to collect the laundry. Akiko in her embarrassment comes in and prevents him from collecting her underwear. The other girls come in as well and finds out why Arashi didn't have her underwear in the laundry. Anastasia asks Akito to come her room in order to help her unpack her things as she's completely incapable of organizing or doing any household chores. During lunch at school, Anastasia interrupts Akiko's attempt at feeding Akito and joins them to eat. Anastasia spontaneously asks to become Akito's girlfriend and confesses her love for him (which she later passes off as a joke). Anastasia also demonstrates to the siblings her version of "three second rule" which causes Akiko to freak out even more. (Source: Wikipedia)
