Honestly, al the low scores... I don't get it.
Was this the best show I've ever seen? No.
Will I rewatch it? Probably not, but then again, I don't easily rewatch a show.
Was the storyline the best thing ever written? No.
Does it have to be? Also no.
Did the actors have great chemistry? Yes, they did. Sure, there are couples with better chemistry, but I have also seen couples with zero chemistry. JoongDunk are solid, but I'm sure they'll improve the more they get to work together.
Are they absolutely adorable together? Yes, they are.
Did the show do what it needed to? Yes. It's a show you can watch and relax. You don't have to have to follow along every five seconds, otherwise you lose the plot. You can just sit down, enjoy it and breathe after a long day of work.
To me, this was a good show. Not perfect, but definitely not as bad as everyone makes it out to be.
