Yuichi, who lives in company housing, has become a daily routine to look into the life of the opposite room from the window of the room. This is because his boss's wife Yuria's defenseless loungewear and bewitching body are fully visible with the curtains wide open. Yuichi has been attracted to Yuria since she was introduced when she came home to take care of his drunken boss. However, the other party is his boss's wife, and Yuichi tells himself to give up on the relationship just by looking through the window.
