Amphetamine

Kafka is straight while Daniel happens to be gay. The young men fall in love, believing that their love can bridge anything, despite their difference in sexuality and Kafka's drug-taking. Daniel does not regret his love for Kafka, who tries to love him back against his nature. But a flashback memory from Kafka's past makes it difficult for their relationship to work. It turns out that their addiction to love proves more fatal than the drugs they use to explore the boundaries of their friendship.
