If you're looking for something with super spanking chemistry and something that will make you laugh your ass off and cry your eyes out (in some episodes only, relax it's not a tragedy show, in fact you'll laught a 1,000,000 times more than you cry ^^), Secret Garden is perfect! I really recommend it! Watched it by chance and was glued to the tv for days! It' sbeautiful and comical, with incredible chemistry and kisses betweenn the leads!
I also recommend Flower Boy Ramyun Shop! It's also really really funny and I love the chemistry between the leads! Of course, Secret Garden is the better :P
