One day, Rentarou, Hakari, Karane and Shizuka went to see the exam results. Rentarou then noticed that he forgot his phone in the classroom. When he came back, he saw a girl was still in the class and had the soulmate shock with her. The girl explained that she did not need to check the results because she knew that she got the first position for sure. Rentarou then went to see the results and knew that the girl's name was Eiai Nano.
Rentarou then tried to have some friendly talks with Nano, only to know that she was extremely cold because Nano considered having fun with other people was inefficient and insignificant. Unknown to Rentarou, Nano actually developed some feeling for him, up to the point that it made her could not focus on her studying. Because of that, Nano decided to propose to Rentarou. However, when Rentarou accepted her proposal, Nano rejected him immediately.

Hearing that, Rentarou decided to burn their photos and end their relationship. Surprisingly, Nano grabbed the photos and kept them from being burnt. Rentarou pointed out it was the proof that Nano gained something so important that she wanted to project.
