I enjoyed most of this drama, but have a hard time dealing with memory loss and time gaps in plots. The last time we deal with memory erasure felt unnecessary and exhausting-- we just spent 19 episodes accumulating experiences with these characters just to have all of that disappear! And usually when I see the "X years later" cut-scene in a series, I start to lose interest. Thankfully, this happened at the very end of this drama, so I didn't have to lose too much interest for very long. Overall, I enjoyed watching, found the characters very likeable, and the plot to be captivating. Bonus points for a happy ending :)
