“Let’s make a warm home!” A renovation × romance drama about building a beloved home together with a gyaru. Kazukage is suddenly presented with a divorce, accused of domestic violence he has no recollection of, and loses the home he could return to. At that moment, a cheerful gyaru calls out to him, “You can stay at my place.” She turns out to be Karen, his childhood friend who used to play “secret base” together with him when they were kids. However, the house Karen leads him to is an old traditional house with years of wear—nothing like what one would expect from a gyaru. While renovating the old house, the two gradually repair their wounded hearts and their relationship, rebuilding them anew. Just like the secret base they once had.
