Not really BL, but more of a realistic LGBT coming of age drama about two boys coming to terms with their truth, and one choosing to be true to themselves while the other buries their true self in order to make their mother happy. There's also a pedophile teacher who became twisted after being punished and rejected by his parents after being found with another boy, who then continued to want to relive his brief fling with boys who resembled his first love. Main boy, who eventually accepts himself, ends up loving one of his bullies. It's a sad and bittersweet story that feels real, but it's beautiful in its execution.
