Romnace - be it period pieces (ie not faithful historical retellings, just period piece, such as My Bratty princess) or rom coms (pasta, hotaru no hikari, city hall); but I like a mixture of heavy and happy (The Princess Man is a good example and I mostly like stories with characters around or in their mid 30s-40s; I tend to watch less 20-something dramas; I like all canonical themes of romances really (aside from love traingles and evil mothers maybe). Oh and donlt usually come looking for dramas with a tragic end.
I like to discover fresh and engaging concepts though, like in Quiz Show season 2 or the Liar Game and am also on the lookout for good non-romance dramas. Tree with Deepo Roots sounds like it may interesting I haven;t seen Cain and Abel yet but I am looking forward to it.
Can't be helped, however I need my filling of happy romance dramas.
