Haven't watched it but I've read some comments about the bad ending perhaps its bcoz it is from the same writers of vagabond which had a bad ending as well.
I dropped it … I love the ML but seemed to boring to continue, especially since everyone said there is no romance..…
Finished the series there are few draggy scenes but I love this .. I need S2.. I suggest you continue this series, the romance bet the 2nd couple is cute.
