Naoya was finally confronted about her behavior in Episode 11, this confrontation took place in a bathtub.
Naoya’s dream harem vacation is ruined in Episode 11 of Girlfriend, Rika’s Girlfriend and surprisingly Shino, Saki’s best friend. When they arrive at a hot spring hotel, their hopes of a relaxing stay go up in smoke when they find Rika waiting for them at the entrance. She followed them to the hotel in hopes of spending more quality time with Naoya, even if it was against the boy’s wishes.
Part of Naoya may have been preparing for Rika’s ambush, but when Saki’s best friend Shino approached him, he was a bit confused. Shino wasted no time before confronting Naoya directly, in front of his girlfriend and Rika, and Saki.
Naoya is able to quickly dodge both Rika and Shino thanks to Nagisa’s quick thinking at the end of Episode 10 when she shields them. She lies to Shino, saying that she and Rika actually went to the hotel together, separate from Naoya and Saki. Yet somehow, Naoya finds herself in Rika’s bath and under the complete attention of his most recent admirer. While he spends all his time with Rika, the young man quickly escapes by climbing the fence with the aim of finding Nagisa and Saki.
Unfortunately, Naoya slips on the roof and falls into Shino’s bathtub. Shino is barely hidden behind a towel, but she stands her ground and quickly reverts to her earlier accusation – that Naoya is a two-time Saki. Naoya struggles to respond to Shino, as he promised Saki that he would not tell anyone about their relationship with Nagisa. Even though he didn’t explicitly say it, Naoya hinted that he was dating both Nagisa and Saki.
Though both he and Shino are in a compromising position over hot spring baths, Shino doesn’t back down on his two-time best friend. When Naoya made the case of how caring he was for Saki and how willing he was to work things out for her, Shino solved it easily by bringing up all the issues in real world when dating between two people. She covers topics like marriage law, consent forms for surgery, and other very real issues.
Naoya doesn’t even think about some of the very relevant issues Shino brings up, which makes her concern for Saki all the more real. At this point, Shino even suspects that Naoya is Saki three times due to Rika’s presence at the hotel and her public confession to him at school. In a climactic moment, Saki and Nagisa stumble across Naoya and Shino in a rather compromising position, and Shino directs her confusion directly at Saki.
Once again, thanks to Nagisa’s quick thinking, she managed to take pictures of Shino to blackmail her into keeping their secret. Shino runs away from the group of three, but one thing’s for sure – she’s definitely not done with Naoya and this disorderly harem.
