LDK manga collects volumes 21-22 in an omnibus format and features story and art by Ayu Watanabe.

Leon's departure from the apartment he shared with Aoi and Shusei leaves a noticeable hole in the couple's daily life, leading them to make a surprisingly serious decision. As rumors abound through the halls at school, the two decide it best to end their cohabitation until graduation, though all it does is lead to loneliness on Aoi's part. Noticing this, Soju drags Aoi out on a date to cheer her up while playing the part of the caring older brother to Shusei, which only leads to more chaos.
