In the classroom, Nishikata proposes a bet where Takagi will lose if she says "cold". He later tries to trick her into saying it, but she thwarts his plan. She then asks him a romantic question, much to his chagrin. Sanae is annoyed with Mina when she sees Mina and Yukari wearing their winter uniforms. Mina then attempts to reassure her that it is warm that day. After school, however, Sanae becomes annoyed again due to the cool weather. Nishikata is eating lunch alone when Takagi joins him. They then have a contest where the winner gets a particular piece of the loser's lunch, which Nishikata ultimately loses. Afterwards, he begrudgingly thanks her for joining him. After seeing a picture of a fake UFO Takao took, an inspired Nishikata decides to do the same thing with a skeptical Takagi. When Nishikata later captures an image on his phone, Takagi realizes the UFO is real. Nishikata is at the public bathhouse when he runs into Takagi. When they leave, a flustered Takagi runs off when Nishikata offers to walk her home due to it being dark. (Source: Wikipedia)
