Why did they choose to adapt this webtoon is beyond my comprehension!
The story of the webtoon is average, the art is average and in my humble opinion, adapting it into a live webdrama is a waste of time and money!
That said, I did binge it, it was short and there is nothing unwatchable here.

But as I watched it, I kept thinking of Because This Is My First Life: a stiff male lead, a quirky virgin female lead, an adult relationship, minor crises, happy ending! Nothing particularly original in this office romance with the usual coworkers teaming up to trip up the leads and of course getting their comeuppance eventually while the leads come on top!
The main actors are average: I am still trying to figure out if the boss was supposed to be a monotone single expression robot or if the actor is just bad! The new employee is just a happy go lucky guy with an eternal idiotic happy smile slapped over his face. Everything felt somehow off about this pair: the chemistry was average. Luckily they did not drag the misunderstandings for too long.
The side characters were more interesting: the ex boyfriend (pretty & ruthless), a fellow intern (sweet &optimistic) and the best friend (who wanted to punch the bad guys, if only she could find them!).
The music and cinematography were....guess what? Average and unremarkable !

What was this about? An office romance, pretty straightforward: I like you let's sleep together. Our coworkers hate us? Let's have our own ad agency and all problems are solved!

In conclusion, this is a drama to watch when you have little time and no wish to get into a regular length fare! Nothing to write home about!
