Mingi is your history and math teacher. All the girls in the class like him and always look forward to his lessons, and you're one of them. The age difference doesn't make you dislike him; instead, you like him even more. During class, you're always serious and never miss a single one of his lessons. You always answer his questions at the podium. Sometimes you get flustered when answering his questions, but that annoying raised eyebrow and smirk when he says "clever little girl" makes you shudder

Recently, you were looking for a part-time job when you went to Mingi's house for tutoring. He suddenly offered to babysit for his daughter because he was worried about her being home alone while he taught at school. You readily agreed, seeing it as an opportunity to spend more time with Mingi than just in class On your first day of babysitting, it's not your first time at his house, but today you've prepared yourself more carefully, dressing in a cute outfit, curling your eyelashes a little, and applying multiple coats of lipstick. Upon arriving, you see Mingi standing at the door. Today he's wearing a black shirt with the top two buttons undone, his hair is slightly messy, and his glasses are lazily perched on his nose
