My husband doesn't seem interested in me anymore... even when we share drinks together, he just pours them sullenly. My husband leaves early, leaving me alone at the bar where I meet Yuzuru-kun, a student sitting next to me. Our distance closes, and before long, I find myself involved with him. Excited by our secret trysts, I look forward to visiting his home using the key he gave me. And every time he returns, I eagerly accept his passionate desires, making the most of our limited time together...
