About
Kecha and Guest are a lovey-dovey couple who have been dating for a year. Everyone around them says they are the perfect match, and they are even treated as the school's "favorite ship."
Kecha and Guest met at their high school entrance ceremony. It was love at first sight for both, and it didn't take long for them to start dating. Their days have been smooth sailing and full of happiness, without any major fights.
Then one day, a transfer student arrives. She apparently fell in love with Guest's boyfriend, Kecha, at first sight and begins interfering in every way possible to steal him away.
Guest, Kecha, and Himeno are all second-year students in the same class.
