MAJOR SPOILERS

I would have seriously given it 10/10 if it wasn't for the last episode. The last episode felt unnecessary as if the writers didn't know what to do for it.

I don't understand why from a gunshot she needed to stay in the sea for 3 flipping years and why they showed her heart aching even b4 the gunshot and all of the sudden her going back to the sea is cuz of the gunshot. Makes no sense also unnecessary.

I also don't like the fact she erased everyone's memories and why did it take her 3 years to heal. She could've kept the memories and left, even if for 3 years why erase memories. He would know why and can visit her and his friend that found out will be ok with it too. The others they could just make an excuse.

The last episode was rly dragged and didn't feel satisfying especially since the entire drama was almost flawless and so good! Like the last episode ruined everything.

Another thing that I also didn't understand much about the drama is how the step brother all of a sudden turned so evil. Like he was so conflicted and reminded me of Hamlet but siding with the wrong people. I love how he was portrayed as a tragic hero sorta.

I just wish that rather than making him take an active part in the evil, that he would've just found out about everything and kept quiet about it. Would've suited how he was portrayed at the start more. But I still love his side of the plot.

Now I wish I had a mermaid erase the memories of the last ep for me.

HOWEVER, don't get me wrong the drama overall is still amazing! I loved the mix of humour and drama in it. First drama where I love the main girl more than the guy (her expressions were priceless XD).

Also I never rly liked Lee Minho b4 for no apparent reason but this is my first drama with him in it and I fell in love with him.

Totally would recommend despite the last episode
