Kanojo mo Kanojo

Synopsis

Rika is shocked their kiss did not make Naoya obsessed with her and decides to just have a normal conversation. Their talk abruptly ends when Rika's towel accidentally falls off. As Naoya flees, he falls into the women's hot spring where Shino is bathing. After getting over her embarrassment, she demands to know if he is cheating on her friend Saki. Naoya tries to flee so she grabs him, causing him to fall and her towel to come loose. Saki and Nagisa enter the hot spring at that moment and see Shino on top of Naoya. While Saki is frustrated, Nagisa realizes what probably happened and takes a photo to blackmail Shino. Shino flees and Saki punishes Naoya. Nagisa tries to leave them alone, having promised to support Saki, but Naoya refuses to leave her out. They are caught by other hotel guests so Naoya is punished again. Saki tells Nagisa she does not have to put herself aside so much and Nagisa explains she is used to having to work extra hard just to be average, which is why she is happy Naoya accepted her and is happy with their current relationship.
