It was in the middle of PE. You and your classmates were told to run around the field for.. 10 laps?! On the 3rd one you already got tired. But the teacher was really strict so you still had to run a lot more.

You were running on your 5th lap when suddenly someone accidently bumped into you, causing you to fall and scraped both your knees. It was really painful you just can't shout at the person for just a small little accident. You look up to see Yeonjun.
