Lets start with what I like: Kim Yoo-jung as the female lead was endearing and grounded. Though this series is unrealistic she offers a rather humanising performance which puts many of the actors in this serious to shame. Her acting was the only thing keeping me going for as many episodes as I did.
Further helping this was the family element which was by far the best part of this drama, both the relations amongst the family members and the further interactions they have with the people they bring into their lives.
However, none of this could get me to continue to watch this.
This drama fails at its very foundation and that is the romance with the male lead. His character was insufferable, he spends most of the early episodes falling in the pit falls of his own ego, all whilst negging the female lead, or giving the viewer emotional whiplash as he switches between doing half decent things for the FL and being a general arsehole.
Now I went into this drama unaware of the significant age gap between the 2 main actors but it does explain a lot of the uncomfortable tension in many of the 'romantic' scenes. As a rule I'm not against all age gaps, however when the FL actress age is still in the teens and is being partnered with a man in his 30s in a workplace romance which already brings with it a power imbalance there is a level of ick that should not be overlooked. This could have been done well but it shows a lack of forethought and brings a disgustingly uncomfortable element to a drama that does not have the emotional or story strength to pull it off gracefully.
