Wrong thoughts

You were an introverted female student who has a soft heart and Jungwon was a senior male student who is cheerful & friendly to everyone. You & him are friends who kinda close to each other. One day, you looked for Jungwon bcuz every morning you will greet each other. You were about to walk into his class when he appeared in front of you with an expressionless face and you saw him not having a smile on his face for the first time.
