My Bias is Showing Season 1 (Complete) (Korean Drama)

When high school teacher Na Ae Joon shows up for work on an ordinary day, he never expects to bump into his favorite celebrity in the hallway. But when his school becomes a filming location for a show starring Choi Si Yeol, his bias from the idol group A-One, that’s exactly what happens! If that’s not enough to give a fanboy a heart attack, Si Yeol takes an interest in Ae Joon and asks him to join the show as his “co-teacher.”
