"Vivid Romance" is neither whack nor excellent. It is enjoyable though quite forgettable,  and short enough not to make you feel like you've wasted your time. It's actually the 2nd mini-series that I have been able to finish. The storyline was interesting, since it addressed the inferiority complex of those who are unlucky in terms of genetics and background. That would have been a good script for a standard drama.  All the actors were good, the male and female leads were excellent, especially actress Jo Soo Hyang who was the bad girl in "Who Are You : School 2015" and left a good impression on me at the time. But I watched this mini-series to see more of Kang Ki Young (after seeing him in "I'm Not A Robot"), who plays Jo Ji-Seob here. He did an awesome job, now I know he's also good at comedy!

All in all it was okay, nothing to write home about, but at the same time fun to watch to kill time. Will I watch it again ? No, like all mini-series everything happens way too fast, since there's not enough time for character development. Maybe this format is just not for me. Would I recommend it ? If your goal is to see more of a certain actor's skills or if you're a fan of one of them, definitely. If you're looking for something revolutionary or at least memorable, then move on to something else.
