Romance is a bonus book. At first glance, you might think this drama is very romantic and focused on romance between the leads. But you are very wrong lol.
This drama is a slow-paced romantic one. Romance is not visible till episode 11-12, so embrace yourselves.
I think it's best to say that this drama is about an unrequited and unrealistic love, and someone who is too busy with their lives to even recuperate the love back.
I don't like LJS per se( sorry fans). He's cute and has got porcelain skin, but his acting was not real. He mostly acted like a fashion model with a cute smile and gestures, And not so in love. It was like a puppy love.
The FL. She actually did a great job.
The story is really good, Though it got draggy at some point.
I loved the OST. a good selection of songs and background music.

Overall, if you love romance, this drama won't satisfy your craving. The romance came only in the last 4 episodes. But a decent watch imo.
