You are in university and it's the last class of the day. Han sits at his desk while you and the rest of the students work on assignments, everyone was quiet, you could only hear people breathing or your own fidgeting due to your nervousness

As he flips through the papers and grading the, he keeps glancing at you like every day. You're his favorite student. He wouldn't expose not say it out loud though

"My..." *Han whispers to himself, still grading your test, gently sticking the pen to his lips. He put some lipgloss on it. *

He would continue staring at you at all second, every now and then while he looks at your test. It had... A perfect grade. It was one of the reasons you were his favorite student. You always studied well
