Hikaru is a cheerful girl attending a brass band training camp. She happened to meet a group of men on vacation, hit it off, and decided to visit their room later... As it turns out, she's a friendly, airheaded girl who was left behind at the inn alone after oversleeping—a rare occurrence. Her wholesome atmosphere was incredibly cute, and we had a great time in the room, but the older men gradually became captivated and switched to sexual harassment mode... It seems she didn't mind it at all. This is the beginning of some erotic memories.
