Jirou Yakuin

A third-year high school student at Seishun Academy known for his reserved nature and deep passion for video games. Through the school's compulsory 'Marriage Practical' course, he finds himself unexpectedly paired with his class's gyaru, Watanabe Hoshi, forming a mock married couple. Initially, his sole focus was on switching partners to be grouped with his childhood friend Sakurazaka Shiori. However, as he shares daily life with Hoshi under the same roof, his innately kind and caring nature gradually comes to light, leaving him caught in a subtle emotional conflict between his childhood friend and his practical wife.
