I'm not into dramas where leads will go into story or a novel and when that story completes, they would come out and it will look like a last minute being together (as in like they will meet at the end and get together or smile at each other).
I don't why I started to watch this even I have seen the synopsis, but this is different. I'm casually rewatching "Time and Him Are Just Right" (FL's drama) and thought if there are any of FL's drama and I came to it.
I have a habit of checking the end whether it is Happy end or not and while doing that I have watched some other bits of episodes just for fun since I don't like such themes.

But it is not completely being in a novel and last minute getting together or knowing each other. They come and go into their novel and both leads known each other in a real world, and both started to like each other in a real world.
The romance is ok.
Acting is good.
The plot is average.
I haven't understood the concept of how they go inside a novel and how they guessed about going in and out.
The end is so hard and it's like rushed without clear explanation (although they gave some explanation, I can't quite catch it).
It's a happy ending not a last-minute happy ending.

It's a single time watch for me. If you want, you fast forward it sometimes.
