If you're a man of culture who likes noona romance then the synopsis will definitely seems intriguing. And the first few episodes will make you go uWu true but after finishing it you'll feel you've been deceived. The utter shithousery ending will want you to pull out your own hairs because you wasted some valuable hours of your life watching this crap.

The plot was great, the age of male protagonist was also doable(in noona romance). All it needed was a good ending. The first 5-6 episodes gives you the impresssion of a great noona romace drama in teh making, but after that it all goes downhill.
Felt like there was no direction. I was wondering whether teh script was completed before they start filming. One or two episodes of cringy romance is acceptable but no, the drama will force you to endure that almost through the whole duration.
So advice will be if you want to watch it, watch the first half of the drama then drop it. Make up your own ending and never touch it, it'll leave a bad taste in your mouth.
All these are applicable unless you're one of those "Goblin" come "Gong Yoo" fan. And it's admirable how "Bae Suzy" pull out her career in k-drama industry after this one. "Lee Min Jung" was beautiful in the drama like she how is does in her past and future works, that's it.
Don't let the overall rating of 7 fool you, that's just work of fanboy/girl of certain actor certainly. Since MyDramalist won't let me give negative rating I'll leave it at 1.
