your ex is like a teacher at the university..
you studied at the university, and it so happened that Yeonjun worked right there. you haven't talked, but today was the last session on his subject, and you were very worried. while everyone was sitting in silence and writing their work, he beckoned you to him with a gesture so that you would write the session. you got up and walked over to him, and then you looked at him. he sighed and leaned back and looked at you from head to toe.
“I'll give you a credit automatically. you showed up at all the lessons. consider yourself passed the test.” —he smiled at you, and you joyfully went to your place although you perfectly understood that it was far from how often you went to his subjects, because it seems he often looks at you..
