Thank goodness, A Reum suspects her husband is more than he seems. Writer Lee Ji Min wisely had A Reum realize that her sweet kind husband, may have hidden and secret depths just like her first husband did. I appreciate she’s not being made a fool with a mid-series shock to learn the truth about Ji Hoon’s profession and later Derek Hyun’s profession. We wondered and learned more about Derek Hyun’s truth. He’s working on opposite sides from Ji Hoon, but is he evil? I’m enjoying the chemistry among our three leads. I’m enjoying the lightness and humor Writer Lee injects into the script and characters. This show is an easy watch.
Kang A Reum (Yoo In Na) realized that Derek Hyun has secrets. Last episode she was shocked by Ji Hoon’s reveal that has was an Interpol agent. This episode she didn’t lose it when it was revealed her husband had hidden activities. She remembered Sophie warning her against Derek Hyun. She learned Sophie dated Derek Hyun and that didn’t faze her. Is her ability to stay calm and cool with the possibility that Derek Hyun has a secret profession evidence of shallow depth of feeling for Derek Hyun or is it secret fatigue?
Jeon Ji Hoon (Eric) realized Derek Hyun put surveillance on him. That wasn’t shocking to Ji Hoon, he wouldn’t be happy if A Reum were involved with Derek Hyun while married to him. Both men took the measure of each other when A Reum formally introduced them. They survived the awkward dinner. Ji Hoon realized Derek Hyun left his phone to record their conversation. Ji Hoon realized Derek Hyun had surveillance cameras in her shop. What will Ji Hoon do to the camera in her shop? Will he notify A Reum?
Derek Hyun (Lim Ju Hwan) has A Reum and Ji Hoon under surveillance. He put a tracking app on A Reum’s phone and a camera in her shop. He put his man to watch Ji Hoon. Derek Hyun realized Ji Hoon’s claim about money for dental work is a lie. He’s right to distrust Ji Hoon. Who wouldn’t question an ex’s motives? I was a bit surprised when the scientist put the overt moves on Derek Hyun all the while claiming he loved his wife. To be fair I’ve seen plenty of male characters make a move on female characters while protesting their actions were innocent when they weren’t. But I’m not sure what the point of this is. Derek Hyun isn’t going to dabble with the scientist whose actions are harassment by many standards.
The second song of the OST is titled “Only You Don’t Know?” and is sung by Lee Min Hyuk:
I rank this episode as very good, 8 on a 10-point scale.
