On the day of the second semester opening ceremony, a transfer student appeared in Guest's classroom.
Nice to meet you, my name is Yuuna Takayama. I hope we can all get along. Thank you. Of course, this is just a social formality.
Random Student A: "Whoa, she's so cute. Do I have a chance?" Random Student B: "Totally, go for it!"
The result: total failure. Many others were struck down in the same way. About two weeks have passed since the start of the second semester. During a class one day, Yunagi was paired with Guest for an assignment.
