(C) Murayama Inu, Chika Fuji/Live Comics ■About “That Genius is Obsessed with His Fake Girlfriend” “That Genius is Obsessed with His Fake Girlfriend” is a wildly popular original work from Live Comics, which has achieved cumulative e-book sales of 500 million yen and over 4.7 million downloads (as of the end of August 2025). The story centers around Hoshino Rin, a woman in her 30s who is cheated on by her office boyfriend and ends up quitting her job after enduring insidious harassment. (Hoshino Rin) With no boyfriend and no job, she finds herself on the brink of disaster. Her brother introduces her to a housekeeping job for Iku Wakatsuki, a “returnee and talented programmer.” Iku is handsome, but he’s rude and distrustful of others, keeping them away. But for some reason, he seems to have taken a liking to Rin…!? Since its release in January 2024, this series has received numerous reviews, including “The illustrations are beautiful and easy to read,” and “Iku’s doting devotion to Rin is irresistible and heart-melting!” It continues to be loved by a wide range of women in their 20s to 40s. It also took the top spot in the 2024 annual rankings and the first half of 2025 rankings on BookLive, the comprehensive e-book store. *1 *2 Volumes 1-25 of the digital single-episode edition are currently available, and the paperback and digital special edition Volume 1 (containing volumes 1-5 of the digital single-episode edition) went on sale today, September 12th. ※1…Comprehensive e-book store “BookLive” announces its 2024 annual rankings https://www.booklive.co.jp/topics/18516 ※2…Comprehensive e-book store “BookLive” announces its rankings for the first half of 2025 https://www.booklive.co.jp/topics/18567 ■Paperback information -Title: “That Genius is Obsessed with His Fake Girlfriend” Volume 1 (contains digital single-episode edition volumes 1-5) -Release Date: Friday, September 12, 2025 -Author: Manga by Murayama Inu / Original Story by Chika Fuji ・Price: ¥803 (tax included) ・Publisher: BookLive ・Publisher: Flex Comics ・ISBN：9784866754581 ■Electronic special edition information ・Title: “Special Edition: The Genius is Obsessed with His Fake Girlfriend” ・Price: ¥803 (tax included) ・BookLive URL: https://booklive.jp/product/index/title_id/10013571/vol_no/001 ≪BookLive is running a campaign to celebrate the release! ≫ ・Campaign Name: Special Edition “That Genius is Obsessed with His Fake Girlfriend” and “The Oppressed Lady and the Impure Duke” New Release Release Commemoration Campaign ・Campaign Period: Friday, September 12, 2025 – Thursday, October 9, 2025 – Campaign Overview: During the campaign period, you can read a total of 13 Live Comics titles for free or at a discount, including the digital single-episode editions of “That Genius is Obsessed with His Fake Girlfriend” volumes 1-4 and “The Oppressed Young Lady and the Impure Duke: I’ll Pay Back That Impurity!” volumes 1-18. ・Campaign page URL:

In fact, Rin may be a femme fatale who drives those around her crazy with her alluring, pitiful aura. So, I’m looking forward to the start of the serialization of the spin-off, “The Villainess is Obsessed with Her Fake Girlfriend.” 【Mafia Kajita Profile】
