Protect the Knight

Ye-eun is a young high schooler who fantasizes about one day having the perfect first kiss with her crush. A practice kiss on her sister's action figure, Bryk, turns her world upside down when it magically brings him to life. Bryk, a once-legendary and definitely human knight, finds himself perplexed as to how he woke up as an action figure. Though he sets out to find the witch who he suspects is to blame, he quickly gets caught up in Ye-eun's attempts to keep her sister happy and her crush interested. Bryk and Ye-eun vow to figure out what turned him into a doll and how to return him to his world as a human man. That is, of course, if he doesn't get broken, eaten, or stolen first.
