For those who don't like drama, this is the perfect series as there is no drama at all. Before I start talking about how I DON'T LIKE ONGSA, I'm going to say what I liked about the series: Aylin and Lua. These two could have their own series. They made the whole series happen.

Now I'll explain why I don't like Ongsa: She keeps making her life difficult and acting like a child. Take a look: She lives in a perfect, loving family, has perfect friends and lives in a perfect school. Her parents are both alive and happily married. They, as well as Ongsa's sister and cousin, live in harmony. When Sun and Ongsa's relationship comes to light, they all accept it very well, without any resistance. Ongsa's friends and school do too. Sun's parents too. Just happiness.

"SO WHEN IS THERE ANY DRAMA?" You may wonder. And I respond: "When Ongsa acts like a 5-year-old child trying to get attention."

For example, when Sun discovers the truth about "Terra", Sun is super open to listening to Ongsa, but instead of Ongsa saying how things happened to get where they are, she simply runs away. Leaving her entire family looking for her ALL DAY! Her family was very worried about her, if they had any doubts they would call the police! All because that idiot Ongsa ran away and hid crying. Then you might even think “This could happen!”, yes, it can. With A CHILD, not a high school girl who is almost AN ADULT.
Sun goes after her (which she didn't need to do, as it's Ongsa who should have gone after Sun to explain herself). When Sun calls Ongsa to talk, what does she do? Exactly, she runs away again. Sun was ready to listen to Ongsa's explanations from the first moment she ran away, now she was open to listening to Ongsa's explanations again and she ran away again. It was Ongsa who acted wrongly, she was the one who deceived and betrayed Sun's trust, she was the one who should be running after Sun, not the other way around! Even so, having two chances to tell the truth to Sun (who was open-hearted to listen to Ongsa's explanations) she chose to run away.

Sun goes after Ongsa for the 3 TIME, and simply gives up asking for the truth (after all, Ongsa might run away again since she is soooo mature), instead Sun decides to simply pretend that they are getting to know each other again and that this story of "Terra" never happened, after all, just so the little baby that is Ongsa would stop running away! Wow, how angry at this girl! She's not ready for a relationship if she acts like a little child running away from her problems.

I keep imagining Sun dating Ongsa, and I feel sorry for her. Every time Ongsa messes up, she acts like a child and runs away from problems, or simply tries to solve problems like a child too. Sun will have to always seder, always choose to "forget what happened" instead of talking about things.

And when Sun broke up with Ongsa why didn't she want to admit their relationship? Remembering that Ongsa's parents CLEARLY showed that they would not be against this, as they found out about Lua and Aylin and were super in favor. Sun was also suffering, but she was silent. So how will Ongsa get her friends' attention so they can comfort her? Acting like a child! She ran and screamed around the court like a child who doesn't have the toy she wants, of course all of Ongsa's friends will run after her to "comfort" her. Our almost 20 year old baby. Even Sun felt embarrassed about it.

I hope Sun finds a better person. Ongsa, until you mature, stay away from Sun, it's a favor you do for her.
