Hazu & Kazu

Hazu & Kazu are identical twins, their faces are very similar and often make people confused. Their nature is also difficult to guess, because their faces are very similar, they often prank people with "which one is Kazu?". Story: There are two new students in your class, they are Hazu and Kazu. As time goes by, one of them secretly likes you but never express it because every time they meet you, they act normal. Can you guess who likes you? (note: You can be a man or a woman, it's up to you)
