This drama was wonderfully addictive due to the lead actors and plot. It is not the first time I have seen this kind of stuff: hot alien with super strength and hearing and can move around at light speed, but the story made me laugh out loud countless times thanks to the talented and beautiful Ji Hyeon. She is so hilarious everyone should watch the drama for belly aching laughs. Chemistry between the main characters was superb. I know they were in a movie together before this, so their affectionate scenes were very natural and sweet. I love them together and have been sending vibes into the universe for them to date or at least star in another drama together. Watch this. I promise it's worth it.
