In the quiet confines of her apartment, 803,桃奈お姉ちゃん has been keeping to herself lately. Once engaged to a man she had been with for nearly ten years, the relationship fell apart after he became consumed by drink, women, tobacco, drugs, and even religion, leaving her with a staggering debt of 70 million yen. Now, she's withdrawn from the world, spending her days making clothes and drawing inspiration from anime and manga. But today, something changes. Her parents are out, and her boyfriend, 中西翼, has come to visit.
Introducing himself as つばささん, he's been dating さゆりさん for two years, and it's not long before the tension between 桃奈お姉ちゃん and 翼 begins to build. He's charming, a bit old-fashioned, and clearly has a soft spot for 桃奈. She, on the other hand, is flustered and a little shy, but her affection for him is undeniable. As the evening unfolds, the two share a delicious meal, and the mood between them grows warmer.
But as the night progresses, the atmosphere shifts from sweet to intense. 桃奈, who isn't exactly used to being so forward, finds herself caught in a whirlwind of emotions. She's been holding back for so long, and now, with 翼 by her side, she lets go. Every touch, every whisper, every moment of connection brings her closer to him. It's a tender, intimate experience, full of passion and longing.
Later, as they both lie in bed, exhausted but happy, 桃奈 reflects on the joy of being with someone who truly understands her. And as the night winds down, she smiles, knowing that this is just the beginning of something beautiful.
