I honestly LOVESS this drama so much, but I give it a 9 because it doesn't feel complete. The plotline could have elaborate more on what happen when there FL was on the island.

They should have made an episode where they retell what happens from the beginning when the FL fell into the sea all the way through until the FL was rescued, that way the viewer could see why the FL was really in love with the ML aside from us knowing that he saved her every time she's in danger and took care of her while she was there.

Overall, I recommend this drama so much to people that want to have a short and simple drama to watch during their free time. It's a really sweet drama with a bit of mystery in it.
