Series by 高瀬わか

A high school boy lives alone with his older sister. Her best friend is always at their home, and her closeness keeps throwing him off balance. She is beautiful, charming, and far too casual about getting near him. He tries to keep up, but her presence leaves him flustered again and again. Their days settle into a romance full of mixed signals and mutual feelings.

Reo is an adult woman who shares a home with Haruki. Haruki is handsome, capable, and unusually attentive at home. He cooks, helps with makeup, and greets her with a sweet smile. Their life together is comfortable but emotionally charged. The romance grows slowly as their domestic closeness becomes harder to ignore.
