第9話: リカに関する直哉の嘘がキスと温泉デートの誘いを引き起こす
Naoya explains why he thought Rika liked him when really she was just in heat, causing her to become furious at the obvious lie and at Naoya for believing it. In the end, she claims to just have a cold. Naoya explains that if she did like him, he would still turn her down so as not to upset Saki or Nagisa. Rika stubbornly tells Naoya she likes him in front of the whole class then drags him to the gym storeroom where she reveals her plan, to keep flirting with him until he falls in love with her. However, when he keeps on refusing, she snaps and kisses him before running away. Another girl from the class overhears this from outside the storeroom. Saki and Nagisa are depressed Rika kissed Naoya first, but Saki decides it was not a real kiss since it was a surprise with no emotion, so when she kisses Naoya it will be the real first kiss. Naoya is confused about everything so he apologizes and suggests a fresh start by going on a date, something they have all been too busy to do yet, so Saki demands a hot spring date.
