This wasn’t perfect, but it was definitely good! The main selling point was the charming, compelling, adorable, amusing main couple (Cheon Song Yi and Do Min Joon) - both of whose actors were attractive people with fantastic acting skills. The plot was okay - some things could have been better explained with the alien stuff, and the murder plot was a bit dragged out at the end. The proper end was also a touch deux ex machina, and again, skimped on the alien/sci-fi explanations/possibilities. That said, I had a really fun time watching this and was definitely absorbed into the emotions of the characters. Also, shout out to Lawyer Jang and Yoon Jae (Song Yi’s little brother)! They were great, too. Overall, this was a solid drama that was worth the watch. Recommended.
