The September 2017 issue of Kodansha’s Bessatsu Friend magazine published the final chapter of Ayu Watanabe’s LDK shōjo manga on August 12, 2017. Watanabe will publish a two-chapter bonus manga in the magazine’s October 2017 and November 2017 issues.
The story of the manga is described as:
Aoi Nishimori is a high school girl who lives alone in her own apartment, but to her surprise, she discovers that the prince of her school, Shusei Kugayama, has moved in next door. To add to this, a series of crazy happenings result in the two living together under a single roof. Shusei is known to be a heartless guy and Aoi particularly hates him after he coldly rejected her best friend, so a life of cohabitation seems like a recipe for disaster. And yet, Aoi somehow can’t stop her heart from pounding when she’s with Shusei.
Watanabe launched LDK in Bessatsu Friend in 2009. Kodansha Comics publishes the manga in English in North America.
