A mix-up at the post office makes two New Yorkers responsible for each other's futures.

Moon loves penguins. Her lifelong ambition is to study penguins in Antarctica. She believes she’ll meet her destined mate just like penguins do. One day, Moon runs into Adley, a guy in a penguin suit fortuitously making penguin courtship gestures at her. She believes the penguin-scented Adley is her fate. As they spend time together, Adley is moved by Moon's genuineness and passion. Just when their relationship has made some progress, Moon is recommended for an exchange program to the UK, throwing Moon into a dilemma between pursuing love and her dream.

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.
