I was really excited when I learnt this had a Korean- chinese couple. That is the main reason made me watch this drama. It also a short drama so, you can watch this within a day.! I wouldn't say i hate it, it was good. It has what is needed, between the 3 couples.
But it could have been made into a better drama with the storyplot it had. There wasn't a language barrier and I liked it. You will find some touching moments, some funny moments and some romantic moments too!
Give it a try if you had time!!
