HEYZO-1680 Do homework with my best friend

Because of his poor academic performance, the young man in the movie always had to rely on his best friend Sakuno to help him improve his studies. But he studied less and "played" more, and he didn't see any progress. On the contrary, he was increasingly dominated by sex because his friend was so attractive, he was always thinking about sex. He also had a good friend who was easy-going, equally horny, and always pampered him like an older sister pampering her spoiled younger brother. The two of them were like a match made in heaven, but they didn't love each other, they were just best friends. Sometimes in life, an ambiguous, unclear relationship is actually good for both.
