I give my 10/10 because I love this story and I watch for the second time.
Felt like I met the perfect 400 years old Alien!
I missed their 7 daughters and 5 dogs!

This drama hooked me from the 1st episode for following reasons:

- Not only a beautiful story but it's not boring to watch;
- The story flow was done great;
- I fell in love with main leads for their beautiful chemistry even though KSY looks bit younger than the JJH;
- KSY's acting was great as an Alien who is mature, brilliant and clam nature where as JJH who is hot tempered and think of high herself but good heart. JJH stole the story portraying her humor and hot temper;
- Also the second main leads connection in the story was well done;
- The songs were amazing but I wish the back ground music change a bit in some episodes;
- Love this story and worth watch it!
