Ikr, the story actually started out pretty good, but as time went by fl and ml were starting to get on my nerves.
Tiara was actually a pretty good character at the start, but somehow her decisions as the story goes on started to really confuse me. She was supposedly 'trained to be a queen since she was a child', but except in the first couple chapters, her behavior and actions simply do not convince me. She runs from situations she can't handle, like literally she runs when finally meets the sequel fl, runs when they unlocked the 'ml soaked in water scene' because she couldn't stop sequel fl from seeing it (seriously tho wut). I just, i just really can't see any queen qualities in her and frankly, i'm kinda disappointed because that was what i was looking forward to.
I don't really have much for Aqua, my opinion is basically the same as yours, i think for a future king his actions are a tad bit irrational, like when he drew his sword on the forest fairy king, dude, that forest fairy king is called forest fairy king for a reason. You do not go around offending kings if you want to protect your kingdom. I get that the scene was to show his love towards fl, but...nah, there must be a better way to handle it instead of violence. Violence is rarely the solution for any problems.
Owh and almost forgot to mention the scene where fl jumped into the middle of the fight to stop them. I had to actually pause to to take in the dumbness of that action lol. Like gurl, unless you're trying to get yourself killed to stop the fight, don't do that. There's a thin line between bravery and foolishness, and with that action you just crossed to the side of foolishness.
With all that said, i did enjoyed the sweet moments, (although most of them very cheesy and how the fl fell in love with ml completely so quickly eludes me, and the ear-piercing one gave me anxiety especially when the piercing went into the fresh hole immediately) and it did provide me an escape from daily life.
Forgive me for the long rant.

I mean, the story is getting real bad. I'm staying for Keith bcs we all know what a fine ass man he is. But I can't stand Tiara and Aqua's relationship.
Like Aqua, make up your mind. Do you want to care for the kingdom or not? He keeps saying he doesn't want to upset Aishira bcs the country will pay the price as the water fairies will get angry but he doesn't care whether or not his country angers the forest fairies? I feel like if he angered the forest fairies, they will take away all their greenery which is essentially taking away their breathing air.
Anyway, Tiara is such a doormat and I can see why her first fiancé was taken from her so easily. She doesn't speak up enough and then she assumes things even if it sounds crazy. She needs to have more confidence bcs her confidence seems almost non-existent. It's annoying.
I wish this story was about Keith now... Bcs like, he is best boy literally. He ain't even a boy, he exudes man fumes guys! In a good way, ofc! It's just so saddening that he had to like a girl who can't do anything...
