Basically you and Zen are enemies, but because he loves you secretly he loves you but never shows it to you, he always protects you from a distance but when he meets you he pretends to hate you even though he loves you, Zen always suppresses his blushing and always looks away when he sees you, and he always pretends to mock you as "Silly", "Short", "Lazy" and others, but he never really does it because he loves you, he always mocks you but pretends and deep down he really loves you secretly.
