Song-song Couple with Yoo Ah In brings Descendants of the Sun to top spot.

KBS drama Descendants of the Sun has once again topped the Wed-Thu prime slot drama- it has been winning 13 times consecutively ever since it was broadcast. Episode 13 brings us more smiles and also shock to viewers. Actor Yoo Ah In makes his cameo appearance in the drama as a mark of loyalty and friendship for both Song Hae Gyo and Song Joong Ki.

Episode 13 has recorded 33.5% in ratings- the highest so far and we can expect more increase towards the finale of the drama...which I assume it is. In the recent episode Yoo Ah In plays as a bank teller when Kang Mu Yeon goes in to apply for a loan only to be rejected. The first thing that Mu Yeon wanted to do after returning from Urk is to send in her resignation letter to the President of the hospital who has once harassed her. She has always wanted to open private practice but requires money. Yoo Ah In's bank teller role Eom Hong Shik (which happens to be his real name) informs her she is denied from the loan and she burst out worrying since she has no job what will happen to her.

Coldly Hong Shik tells her what he should do is attend to the next customer on queue. Hah!

Many fans have speculated that Yoo Ah In might play the role as Mu Yeon and Myeong Ju's school crush Yun Gi but turns out to be a twist. Gritting her teeth, Mu Yeon returns to the hospital to ask back for the job from the President while he just smirked at her.

Back to the Alpha Team, upon their return to South Korea they are now assigned to NIS dept. They have work to do which is to protect the VIPs or special people. Often Mu Yeon and Shi Jin would text each other or talk all day long. The Alpha team have met their match of the day- the top North Korean soldier is back for revenge. While Shi Jin and Dae Young were cracking up, they met this stiff expression from the mysterious men who gave them wound shots. 

Mu Yeon working as usual in the Emergency Room was attending to patients when marine radio called in stating an emergency case. As they wheeled in the wounded Shi Jin and Dae Young into the ER room, Mu Yeon was shocked to see both bloodied and unconscious. The mood doesn't look good for both ends. 

Will both soldiers survive and live another day or will we see a sad ending? With the 40 seconds of Yoo Ah In's cameo it has definitely drove fans frenzy. And seriously working as NIS guards, why can't they wear bulletproof vest under their suits? It's a dangerous job and isn't safety a top priority?
