Leia and Renka are busy with work, rarely having time off together, and despite living together, they continue to drift apart day by day. Then, after a long time, they finally get a rare day off together—just the two of them. On a quiet Sunday afternoon, they lazily spend time together, cook dinner side by side, and talk while soaking in the bath. Through these ordinary moments, their hearts naturally draw closer, allowing them to reaffirm their feelings for each other. Because they truly understand one another, the warmth found in these simple, everyday moments brings nothing but pure happiness.
