Kotori Yukan, a student from Beichuan No. 1 Middle School, met a netizen named Onigiri on the Internet. Kotori Yuharumi, a twin sister who lives far away in Qingxue, didn't learn from her sister until the day she started her first year of high school that Yukan had been in a relationship with Onitan-kun for half a year. Fortunately, Oniguan-kun himself had sent his name and photo honestly, but he looked more and more like the twin brother of the setter who was in the same class with her... So, would anyone really be so honest on the Internet?
Intention: The Internet is a thread, cherish this fate.
