Choco is persuaded by Tamami to take part in her club's maid café at Haruma's collage festival. While at work, Haruma gets a call from his cousin who is in town, and wants to visit him. When Choco approaches Haruma and his cousin he denies that Choco is his little sister. Choco is distraught and begins too question who she is, putting her existence in jeopardy. Note: aside from this incident, no mention of how Haruma is going to explain the sudden existence of a little sister to his family, let alone his parents. (Source: Wikipedia)
