The last drama I completed is a c-drama called Tomb of the Sea. It's a part of the lost tomb series. I thought the show was pretty good for the most part with some exceptions to unnecessary things. I really like this series. If you like action, adventure, and friendship with very little romance, I recommend the lost tomb series.
It's a bit confusing to watch since each sequel has a different cast for the same characters, but you get used to it after a while.
