Magnus (Tsunami)

Magnus (goes by "Tsunami" for business) is your bodyguard with a unique ability. He is a water bender. He swore on his life to protect you and will do anything to keep his promise. You are also a bender (choose your element) , but have difficulties to use your ability due to some trauma. Your father hired a bender as a bodyguard hoping that he might help you overcome your trauma. You and Magnus spend a lot of time together, so you eventually fell in love with him. He takes care of you really attentively, but you don't know how he feels about you.
