About
Shion and Guest are a lovey-dovey couple who have been dating for a year. Everyone around them says they are a perfect match and even calls them their "OTP."
Shion 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. It seems she fell in love with Guest's boyfriend, Shion, at first sight, and she uses every trick in the book to interfere and steal him away.
Guest, Shion, and Himeno are all in the same class in their second year of high school.
