I started watching this drama because of the FanFan couple (from drama Be Yourself) and I was not disappointed.
The story was different from the typical c drama and it was fast pacing but well executed tho. It had flawed and pretty realistic characters and a very different storyline.
A homebody with social anxiety and a rebellious girl find mutual healing and salvation while on the run. Through each other, they find themselves again.
The music and main lead's acting were really good.
The plot has a lil bit of romance, action, dark comedy, bonding and keeps you engaged through out.
This drama is definitely underrated, it deserves more.

So if you're confused about whether to watch this drama, just give it a shot. Trust me, you won't be disappointed.
Besides it's just 8 episodes and that too 20-22 mins each episode. You could binge watch it in one sit itself.
