I am an ordinary high school student, Shingo Fujishima, and I have a childhood friend who is known as a divine actress in the world. We live in different worlds now, but she seems to be dependent on me and still comes to stay at my house often. We are very close, but she is just a childhood friend. From my point of view, she is like a sister to me. One day, she told me that she wanted to practice a kissing scene, and I realized my feelings for her.
