What happens when your ultimate K-pop bias walks into your classroom? For Na Ae Jun, a 29-year-old high school teacher and devoted fan of the idol group A-One, this daydream becomes reality when his school becomes the set for a variety show starring his favorite idol, Choi Si Yeol. Desperate to maintain his professional cool, Ae Jun hides his fangirl heart, but Si Yeol seems oddly interested in him—flirting, seeking him out, and blurring the lines between scripted reality and something more. However, Si Yeol isn't being entirely honest: he has a hidden agenda tied to a painful past involving his best friend. As Ae Jun gets swept up in a whirlwind of sweet moments and awkward encounters, the truth threatens to shatter the fantasy. With a towering height difference, an adorable second couple, and a story that balances fluffy romance with surprising emotional depth, *My Bias Is Showing?!* is a joyful, serotonin-boosting series that asks: what if your bias became your boyfriend, but at what cost?
