My Longtime Friend's Daughter, Whom I Secretly Love, and My Mother... I'm Addicted to Freshroom!?

Rokuro, a male student, is troubled by his stagnant relationship with Ryoka, a beautiful friend from long ago. He fears that after graduation, any connection between them will vanish entirely. When Ryoka accepts an invitation to visit a mysterious venue called "Freshroom" run by an enigmatic solicitor named Sakura, she is drawn into a surreal space inhabited by three masked figures. There, Ryoka experiences bizarre and invasive encounters. Rokuro must navigate this twisted realm while encountering his own mother—a character returning to the Sarobetsu Galaxy series for the first time in years—and determine whether he can escape Freshroom with his sanity intact.
