It is a nice drama if you think of it as an original series. As someone who read the webtoon twice, and loving it for the simple honest conversations, the relatable aspects and characters... It takes a lot of turning around to watch the drama.
The Dinner Mate is totally different from the webtoon, characters' personalities are completely different. A lot of excess drama added in. The difference between the girl's and the guy's dating history are no longer as stark. The acting pulled off the show, but the storyline disappointed me.
