Let me be very clear on this. This is NOT a romance between two characters. This series spits on your ships.
This series is an interesting combination of Lashanu, Kyou Kara Maou, & Hetalia. Like Lashanu, the mc is cursed in love & immediately goes after a new love interest without hesitation. Like Kyou Kara Maou, it is a harem series with a young king on his first year of the throne & during an impending war. Like Hetalia it's a gag series with lots of shipteasing & no hookups.
So like a lot of Chinese webtoons, it starts off as a gag series, then it starts getting a serious plot.
The MC is a lot like a woman in an 80s rom-com or musical. She always picks the badass stranger & snubs the loyal childhood friend. You stick him in a room with beautiful men, & he's like a kid in a candy store with a belt full of quarter rolls.
Zhuo Qingliu is not quite a secondary protagonist, but a highly recurring character. He has a crush on the emperor despite knowing how shallow & disloyal he is. He is the emperor's most trusted advisor & he is cursed to have his heart broken over & over again, just like his master. Fans have given him the nickname "Orange" & tend to prefer him over the MC.
Currently, there are not enough translated chapters for me to summarize the war story.
