Review of A Lull in the Sea

Pardon me being lazy on my grammar. So when i watched the first part of this anime, I was amazed why did I drop this anime 2 times... The world, The people, THE MUSIC, all of it was amazing. [spoilers] Then the time skip happened and this is where I just didnt enjoy it as much.Miuna and Sayu was the part that made this anime very hard to watch.
I get it when you were 9 years old you liked Hikari, but it feels so unrealistic when Hikari comes back from the ocean and the feelings for her STEP UNCLE are so fucking deep... like when you are 9 years old i dont think that you can love someone to an extent as Miuna loved Hikari and wait for him 5 years and say you still love him, because a normal 9 year old would probably forget those feelings in 1-2 years... The same goes for Sayu and Kaname.
At that point it just felt like the anime was forcing itself to feel deep and it was unenjoyable, BUT that doesnt change the fact that the first half is 10/10 on every aspect.

First half:

Second half:
