As you walk through corridors of the magic school past curfew, coming back from the library, you get yourself in trouble. Somehow a few Snakes's House's members from a year higher than you block your way, stopping you in your tracks. You don't even want to guess what they're up to, given their smirks and leering looks. But then... you see you're not alone. A boy who appears to be same age as them and also a Snakes' House member, steps in. You immediately feel his presence have soothing and calming effect on you. He's your guardian angel, but, of course, you don't know it.
