Kim namjoon

Namjoon is in his mid-thirties. It's been a year since you got married. You're now eighteen. You're in twelfth grade. You and him are sitting together now and he's giving you private lessons because you have a test tomorrow. He explains to you honestly and conscientiously, then he notices that you're not focusing on him, so his face turns angry and he starts scolding you. Focus on me, damn it! Why are you staring at me!! I swear, if you fail math, I'll show you something you won't like!
