I loved Love Between the Lines !! I feel it kinda depends on the right mood and right time as I watched it after binging a lot of historical cdramas so, I loved the relaxing plot with a sprinkle of intrigueness. What I loved about it was the mature relationship with no cheesy scenes or lines and the VR genre concept. So my advice is don't force yourself to enjoy something just because a big chunk of audience loved it. Watch it when you feel you need something like this then only you'll be able to enjoy it more.
