The drama had a nice concept but the story was too thin for a full run drama even with the added side stories. It's also why they sneaked in a useless love pentagon that didn't get anywhere. Although you may find the FL's behavior passable as a teen but that wasn't the case as an adult, it was increasingly challenging to endure watching her. It simply didn't serve the narrative. After seeing her character in action I had a strong hunch to why they broke up. Such a reason may be valid when written adequately but, in this case, it came off as a shallow excuse to progress the plot. Even if we were to over glance that, they ended up giving a half-assed resolution to their underlying problems and opted to supplement the rest with an overdose of mindless lovey-dovey scenes while eliminating any opportunity for the drama to delve deeper into the emotional package they threw at us earlier on. Another prime example of the bait and switch technique the Kdrama industry have been going through recently and it doesn't look like this will change. One last thing, there were some obvious amateur editing mistakes sprinkled in the drama. One singular scene may have multiple camera angles but 2 different color grading, even for the same consecutive face shot.
