I dropped it at Ep10, because it is as you said... Cute but silly .... But that is just my taste, I prefer raw emotions, complex characters, over "cute" scenes.....
Also,the female lead is typical doormat and lacks intelligence ... As usual, doormats are dumb, clumsy, hard-working, stubborn, sweet and very cheerful/optimistic ... and to cinch her appeal, she is feisty w/ the male lead... and often acts like a "noble idiot"...:P:P:P
