Contains Spoilers for Episodes 11-12

A new girl shows up at the palace, and she's Shin's older sister Princess Hyemyung, returned from her travels abroad. (She's played by actress Lee Yoonji, who I loved as Teacher Shi in Dream High and as Jaeshin in King 2 Hearts. I like this actress so much, and I didn't even know she was in Goong!). It does seem weird that no one mentioned Hyemyung before, except Queen Mother referencing her once. She has been off doing diplomatic and volunteer work, and the household servants love her, so that is our cue that she is a nice person.

A Nice Person With Not Nearly Enough Lines.

In the enthronement plot, Yul's Mom's spies have given her photos of Shin getting close to Hyorin and being kissed by her at the Thailand airport. Good. I hope his name gets dragged through the mud because of this. I don't want to see Chaekyung hurt if these photos are revealed, but it would be a better alternative than Shin going along like he's doing nothing wrong. I hope I don't gloat too hard when he gets his comeuppance. Ah, who am I kidding?

I Will Gloat Like the Madness When He Gets Paid Back.

Chaekyung gently asks Shin whether she was supposed to marry Yul. Shin looks troubled and admits that her original fiance was Yul, then he gets huffy and asks if she's disappointed in the way things turned out. But Chaekyung's a bit sick and she has fallen asleep already. Shin leans close to her as she sleeps. So...he does have feelings for her, but does that change anything? It's a nice cuddling moment until Shin's mom walks in. I can understand a mom frowning at cuddling teenagers, but what if those teenagers are also married? Do you still get to level the disapproving frown at them?

Apparently So.

The Queen yells at Shin for the first time! Wow. She's not so composed when the servants aren't watching, eh? Mom waits until Chaekyung's gone, then throws down a Thai tabloid in front of Shin, displaying pictures of him traveling with Hyorin. Oh yeeeeeaaaah, he's in so much trouble! I now feel like Shin's kid sister, ready to tattle on him for every offense. But seriously, he deserves a big 'ol falling out and this is the first time I've appreciated the Queen's ability to make someone feel lower than a worm's belly.

Chaekyung sees the newspaper and questions Shin about it, but Shin says he doesn't have to report everything he does to her, and that she didn't need to know about him meeting with Hyorin. Chaekyung takes the smart route and says that if his life is none of her business, then hers is none of his.

Maintenance of His Teddy Bear Is Still Her Business, Though.

Now everyone at school knows about the pictures. Shin looks like a cad and Hyorin looks like the Other Woman, but Hyorin still sees Chaekyung in the halls and smiles with a little "Annyeong!" wave. Hyorin's now hurting Chaekyung on purpose by saying things like. "I don't care about being the Crown Princess, I just want Shin." From a combo of sickness and sadness, Chaekyung faints at school. Shin comes to the rescue and carries her away, then tends to her when she's sick. He does it while stylishly dressed, of course.

This Guy and His Bow Ties, I Swear.

Chaekyung's parents visit their sick daughter and ask Shin if they can take her home to recover, Shin says he understands, but he's going through some tough times and really needs Chaekyung by his side. He plays up his jerk quotient and tells Chaekyung that she cannot go home because she must follow his wishes. But the jerkish statement was not entirely true: when he is alone, Shin sadly says, "If I let you go home now, you'll never return."

Shin says to Chaekyung that when he comes of age, he'll resign as Crown Prince. But part of me wants Shin to step up and do a great job as king. He always seems to be running away from things and ducking responsibility if he can get away with it. Wouldn't it be great to see him become a true grownup? Shin meets with Hyorin and finally breaks things off with her permanently, but then he has to be an idiot and turn down a special cake Chaekyung has baked for him.

All Those Hours in Home Ec, Totally Wasted.

Yul has been questioning his role in bringing down Shin, and he tells the Queen Mother that when his father is enthroned posthumously, he still wants to be just another prince in line for the succession behind Shin, not in front of him. Hmm, what does he have to gain by this move? Seems like Yul is trying to figure out a way to get Chaekyung without becoming king. Yul's Mom is angry when she hears what he has done. Yul finds her lying dramatically on the floor, and when he panics she says, "What? Did you think I'd try to kill myself again?"

Oh, the Mental Instability Now Rears Its Head.

The King faints at the posthumous enthronement ceremony, and Yul discovers that his mother is slightly crazypants.Yul's Mom warns Shin to be careful of attacks outside the palace. Shin astutely says he's more concerned about attacks from within. Chaekyung goes into Shin's photo room and finds an entire book full of nothing but Hyorin pictures and keepsakes. (Chaekyung, honey, it's time to get away from these royals. Yul's mother is insane and possibly violent, while Shin is a cold, aloof waffler. Shin is officially such a louse that his prim, emotionally distant mother tells him to be kinder to Chaekyung.) Anyhow, the last episode kind of trails off with Shin making another stab at being nice to Chaekyung.

But You'll Never Be As Nice as Yul.
