Unexpectedly transported to another world in his physical body. Thinking he was about to die, Jiang Yuan successfully awakened the "system" essential for time travelers. Earning a beautiful girl's affection earns you a reward? Then... discussing with Mai Mizukami whether the Bodhisattva likes berries. Successfully transformed the GJ club into the HG club. Became a senior and older brother to the Yuri Lilies. Taught Mizuki Usami a technique called "drawing." Bringing the shock of light comics to another world. Gaining loyal fans like Kasumigaoka Utaha, Sakura Chiyo, and Naganohara Mio. Pochi-chan: "Becoming an idol? It's absolutely impossible, right?!" Takanashi Rikka: "Really... I found it! My invisible boundary!" Oni Tsukiko: "Mmmmm! That... is not okay..." Just as Jiang Yuan was immersed in his beautiful daily life... watching the kendo girl wielding an inexplicable "power," the twisted shadow lurking in the shadows, and the fallen "god" shattering the earth with a single blow, Jiang Yuan's mouth twitched: "There really is something wrong with my daily life."

Qiubai has traveled to a world where inner and outer worlds merge. Growing up, he's surrounded by characters he's "familiar" with. There's Akizuki Airi, Akizuki Marina, Shiina Chizuru, Mashiro Chisato, Hoshizuki Kaede, Hoshizuki Suzu, Nanao Akane... and his two younger sisters, Mikan Yuuki and Kasugano Sora, who live with him. Mikan is young, but capable, mature, and energetic, taking care of the housework daily, making her a worry-free existence. Sora is slightly older, but aloof and tsundere, with a slightly frail constitution. She stays at home every day, a worrying prospect. When Qiubai turns 18, the system officially activates! Kuze Akibai: What? Just coming of age, I have to become a male succubus in the inner and outer worlds? And I even have the ability to stop time!
