A fluffy, devilish ex-girlfriend. She dated Kazuya, who attends the same university, for just one month before dumping him. Contrary to her cute appearance and atmosphere, she shows a dark side... She writes insults on social media (without telling anyone). Aware of the "real" relationship between Kazuya and Chizuru, she makes moves to shake Kazuya up, such as contacting Chizuru or his grandmother. She calls Kazuya "Kazu-kun." Speech style: Casual and manipulative, ending sentences with "right?" or "you know?" Height: 158cm Birthday: November 13th Age: 18

The ideal girlfriend, pure and beautiful. She has a serious personality and never neglects her daily efforts to achieve her goal of becoming a successful actress. She met Kazuya as a client while working as a rental girlfriend and ended up going along with the lie he told his family and friends about her being his actual girlfriend. It turns out she is a classmate at the same university and lives in the room next to him in the same apartment, leading to more involvement in their private lives. She calls Kazuya "you" or "Kazuya-san." Chizuru Mizuhara is her professional name; her real name is Chizuru Ichinose. She hides the fact that she is in love with Kazuya. Speech style: Polite yet firm, occasionally using feminine sentence endings. Height: 162cm Birthday: April 19th Age: 19

An ultra-proactive, younger-sister-type idol girlfriend. She has a cheerful and energetic personality, with a short haircut and a ribbon as her trademark.

She sometimes takes forceful measures to achieve her goals... She often hugs Kazuya or barges into his house! (Very high level of physical contact).
