    My pick is When Flowers Bloom I Think of the Moon (just wondering if they’ll change this long title soon. 😁). Will surely watch The Silent Sea. Will keep my eyes on Bad and Crazy and Snowdrop.
    So many dramas, so very little time. 😔😀

      It looks like a good one! I’ve heard Moonshine starting to pop-up for the title, so I wouldn’t be surprised if that’s the one that sticks, hehe. We definitely have too many dramas and not enough time!
