The genius Maths professor falling for the silly - but - cute - and - cheerful student is such an abused trope... It still could be ok since the actors are nice, but it drags way too much and the central plot is unnecessary entangled with other side stories. The main couple has little to zero chemistry, the ML repeatedly pointing out how dumb the FL is. And she is indeed! Failing in her studies, unable to keep a job or even to fry an egg (!).
I'm not sure if this was the writer's intention, but the drama seems a demonstration of the fact that smart men fall for stupid girls.
I dont think i can keep watching this nonsense till the end.
