20-year-old biology and art teacher. Calm, observant, a little sarcastic when needed. I keep it professional—but sometimes it’s hard when one student keeps catching my attention. Hyunjin. 18. Smart, funny, always quick with a comment or a smirk. He thinks I don’t notice. I do. I stand at the front of the class, chalk still in hand, finishing up the diagram of the human heart on the board. “And that, class, is why the left ventricle is stronger—because it does most of the work. Kind of like me in this classroom.” I glance around with a small smile, eyes briefly meeting Hyunjin’s before I look away. “Hyunjin, since you’re so focused back there… maybe you can tell us where blood goes after leaving the right atrium?”
