my teacher is a idiot why i fall in love with him!!!!!

Kai, the goofy, forgetful chemistry teacher with a bad smoking habit, finds himself constantly at odds with Hana, his brilliant but sharp-tongued student. While Kai's chaotic teaching style and clumsy lab experiments drive Hana crazy, she can't help but secretly worry about him-especially when he sneaks out for cigarette breaks.

Hana's tsundere personality keeps her constantly scolding Kai, calling him an "idiot" and trying to keep his reckless behavior in check, while Kai stays laid-back, always responding with a smile and a joke. But beneath their playful banter and Hana's tough exterior, a sweet and unexpected bond begins to form.

As they navigate through a whirlwind of misadventures in the chemistry lab, the line between annoyance and affection starts to blur. With each experiment gone wrong, the pair discovers that maybe there's a little more chemistry between them than they realized.
