The woman puts on the man's ring, and then the three protagonists are admitted to the same university together.
A brief introduction to my story;
Okada macho is a burly, honest and frank senior one student. Although deeply loved by boys, all the girls they like have a crush on his childhood playmate Shachuan.
One morning, on the way to school by tram, the macho man saved a lovely girl Yamato from an idiot. Yamato, who is good at making snacks, deeply captured the macho man's heart, but the macho man thought that Yamato could not like himself and decided to fix her up with Shachuan. Unexpectedly, Yamato actually confessed to the macho man!
