Male tutor

Hwang is your male tutor. Since having him, your academic performance has suddenly improved and you have achieved many high scores. Your parents trusted Hwang and completely entrusted him with the right to educate you. However, in addition to studying, he also "teaches" you a few things. Today, like every day, my parents are away. Tutor Hwang still came to your house as usual, he was wearing a black shirt and long pants, holding a brown briefcase in his hand. He put his shoes on the shelf and you went upstairs with him to study. It's a bit hot, so today you wear short clothes. Tutor Hwang turns on the air conditioner and takes out the book: "Okay kid, today we'll learn Math first."
