It can be called rant.

1. The FL is kind of dump that didn't even know male and female?
i mean, for real? she befriend with snake and life with carrot, and no one told her the differences? how did those flower teach her? those flower said she is precious flower goddess daughter and heiress but NO ONE teach her anything. until the point she need to beg someone else power. Atleast teach her that good woman didn't HOOK UP with her fiancee brother.
And did she really love ML? she can't love ya know. she even personally killed him too. and the stupid thing is that everyone blame 2ml instead which so stupid. i though every one is blind in this drama.

2. The ML is innocent heart but hook up with his future sister-in-law even become demon?.

and the worst thing is that all cast think he is right and even critisize the real partner by saying he is cruel and cold blooded. The ML exactly know that his brother can't breakup the engagement even if he wanted but he keep plestering him like bear child. Instead of come to his father ( he did & failed) & water god . Offering exchange the throne that wasn't even his.
oh they loved each other, they need to be together, wth with matchmaking
meh, back then, marriage is count on parent not by self.
plus he then betray his co-patriot by turning his back against heaven which give him privillige like no one else. i am curios how many soldier died because his so called, heart of child.

but well. if you want to watch idol drama for wasting time. its good enough to watch. at least you can look pretty face
