Ok the first part may be terrible bcs of the blackmail and i thought the student will become somehow a piece of shit but as the story moving on.. I REALISE TENSHI IS SO WHOLESOME. He is actually half angel and half devil so don't talk shit about him. He maybe an idiot for the blackmail but he's actually so sweet. The prof is so sweet too. Love them nevertheless
