Do you need to watch the first season before watching this one? Well, only if you want to understand why Ep 1 of S2 starts like that and the flashbacks from S1, though it only happens a few times, mostly towards the second half of the drama. Otherwise, if that doesn't bother you much, you'll be okay as the plot is about the same.

I personally like this season over the first one. Though I still have to give the story plot a 3/5 stars because it's mainly a copy from the first season. However, there are some things that I liked that they did better in this season.
* Fang Leng & Fang Lie have a great stepbrother relationship
* Though Fang Leng still has his weaknesses, he's a much stronger character here and suffers less. He has more character personality here than the 1st season
* Xiao Qi, while she still has her dumb moments, she has a lot more smart and sneaky moments as well.
* Romance: I can sense more of the love Xiao Qi has for Fang Leng here than I did in S1. It felt like she instantly loved Fang Leng towards the end in S1 but here, it ended up being a gradual liking of Fang Leng. Also, Fang Lie has his own love instead of being in the love triangle with the leads in S1. Three couples in total.
* Xiao Bu has a human form and not just being a turtle.
* The sisterly bond of the 3 ladies.
* The evilness still exists in this drama but has toned down a bit
* Ending was way better than the S1. A picture-perfect ending.

Things I didn't like:
* Bad guys don't get punished for their evil deeds: This is still the same from the first season unfortunately
* Change of heart of the bad guys without any scenes showing remorse or apology. This doesn't make sense to me as it seems like they don't acknowledge what they did was wrong.
* Poor writing for the character Shi Yi: Either make him a villain or a good supportive guy, not in the middle. He had moments where he seemed like a good guy questioning his planet's missions but other times, he longs for power and his one-sided crush.
* Forgettable snobby girl who likes Fang Leng: This girl was useless as she just disappeared from the drama completely after being in a few episodes, being fake nice and eventually rude to Xiao Qi. You can easily take her character out and nothing would change. Not even worthy to be consider a SFL or part of a love triangle. Not sure why the writers included her.

While it's not a top 2022 favorite for me, it's still a funny drama overall. Sure the pervy scenes might be a bit too much and there are some frustrations within the first 15 episodes but still a decent drama to watch in your spare time.
