Kitagawa Yuu, who traveled to the world of anime, originally hoped to achieve financial freedom quickly by relying on the songs he remembered from his past life, and to find a beautiful girl to always be by his side. However, as his "talent" continued to unfold, he suddenly realized that there seemed to be a bit too many beautiful girls who liked him. So... "I'm so sorry! I really didn't intend to have a harem!"

After traveling to the world of the romance anime "Horimiya", he became the only male character in the show who didn't have a girlfriend - Iura Hide. Now Iura Hide felt unbalanced. Everyone is in a romance comedy, why is he the only one who is single? So Iura Hide set a small goal for himself. While working hard to achieve financial freedom, he must first find a girlfriend before graduating from high school and enjoy a sweet campus romance. However, as he got to know this world more and more, he suddenly realized that this world didn't seem to be a simple world of "Horimiya". One anime character after another appeared, and Iura Hide's eyes lit up. "It's decided! You are my girlfriend!"
