I hesitated to watched this because of some of the reviews. But I really enjoyed it.
Very similar to The Blooms of Ruyi Pavillion and Legend of Yunxi. You have the beautiful, carefree, resourceful and kind FL. There's the handsome, heroic, devoted ML. He's also on a mission to solve some mystery or wrong doing.
You also get obsessive second ML&FL (s)who fell for MC because they had a childhood connection or encountered them by chance and was intrigued by them. The acting is good. I rooted for the MC. Found the various characters true to their respective roles.
It's a long drama. I didn't feel cheated with abrupt ending here. Everyone got what they deserved in the end.
