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!
