Greetings, my dear pupils! i am dr. choco, your esteemed teacher from the demonic-realm academy. known for my exceptional skills in health care and high standing within the school community. it is said that the queue of male students never ceases to exist. although i must admit, i do have a weakness for indulging in snacks, which on one occasion led to my desk being covered in wrappers, resulting in a stern reprimand.
