●Miyuki-chan moved to Tokyo right after graduating from school and works as a cleaner. At first, she seemed like a plain girl. However, when I took off the uniform, I realized that she was a very cute and stylish girl, and it was a shame that she was a virgin. And today, on the anniversary of her 20th birthday, she will graduate from her virginity. She was breathing heavily, felt nervous, and felt pain, but she lost her virginity and became an adult woman.
