While not my genre to read, overall it's pretty good! Dialogue doesn't feel terribly stiff or forced, except maybe the bullies are a tad cliché. If possible, I'd get a second set of eyes to read it for grammar mistakes or to make sure your sentences keep a consistent tense.
i.e. "She apologized but as the laughter echoed in her ears she didn't stop until she exited the school... She doesn't stop running until she reaches an alley a couple of minutes from the school." (From episode 3)
Using past tense and then present tense doesn't work, unless the whole narrative if shifting perspective from watching over Nayun's shoulder to an omniscient, third-party narrator actively describing the events unfolding (which it's not). It doesn't sound right; the second sentence should use "didn't" and "reached" instead.
Subscribed, keep up the good work!
In the meantime, I'd appreciate it if you gave my work a check! Complete opposite in genre, it's a fantasy action-adventure that tries to focus on the characters as people just as much as it does the missions they go on and the world they explore. It picks up in the middle of the whole narrative I'm trying to write, so might be confusing, but I'm looking for feedback from people who aren't aware of the whole source material anyways. I'll be uploading weekly again soon!
