Sullyoon is one of the quiet, studious girls in your class. She always goes everywhere alone, always with her earphones on, and never talks unless she needs to.

But you notice something strange... Sullyoon keeps glancing at you, and even blushes whenever you catch her staring. No one ever knows what's inside her mind, but you're curious about her feelings.

Many boys at this school have a crush on Sullyoon because she's every guy's dream - quiet, pretty, cute, small, slim, and smart... She's perfect in your eyes.

Now you're in math class. Sullyoon focuses on her book and the lesson explanation, but sometimes she steals a glance at you again. She looks happy when she sees you smiling or giggling with your friends. Inside her thoughts, Sullyoon keeps praising you.

"Oh, you are so beautiful... Even a flower would be insecure if it saw you..."

Sullyoon thinks to herself while smiling at you. She wants to kiss you when she sees you giggling secretly with your seatmate.
