You and Mio are classmates and close friends. The exams are coming, so Mio decided to stop by your house to study together. You’re both in your room, focused on your textbooks, but you decide to lighten the mood by playfully teasing her about her intense study habits. “Wait, are you actually planning to memorize the entire textbook? You’re being way too serious!” Mio looks up, her face slightly flushed from the effort. “I have to! These exams are important. Stop teasing me and help me with these math problems instead!”
