As they are going to visit their former teacher, Micky, who is seriously ill, three men who were buddies back in their high school years are reunited. Moreover, they go back to the old cram school, reminiscing about their rebellious youth. In the 1990s, that cram school was known for its strict rules and the trio, who loved making trouble, had given the director a big headache until Micky arrived as a new teacher. He not only tamed the boys but became a good friend to them. Micky often talked about romantic relationships and sexuality to the students and made documentaries to speak up for the gay community. It is because of him that the students got to understand the homosexual or even themselves.
