PROLOGUE When I was just 6 years old, I always dreamed of becoming a dentist. I always admired the beauty of dentistry. Despite the perception of other kids that dentists are monsters, I've never gone to a dentist even once, I was scared. Funny isn't it? But what made me love dentistry is I wanna fix my own teeth. As a kid who got bullied about my appearance, I once dreamed of becoming one just to fix my teeth without spending much money. That's how naive and innocent I was. When I was in first grade, I admired how passionate my teacher was to teach. Her voice, gestures, and the way she writes on the board... I wanna be just like her when I grow up. But what would be my destiny? To be a dentist that I used to love or to be a teacher?
