Heeram, who was introduced to a well-paid tutor, went to say his first greetings when he met a kind old man and a half-naked young man who appeared before his face. Even though it was embarrassing, the tutor said something surprising to Heeram, who started taking the class because it was difficult to find part-time jobs like this... "That guy... he's not my father, he's my lover?"
