Zhao Lu Si (female lead) is very funny. I just love her acting this type of character so definitely you'll enjoy the comedy.
To my surprise Ding Yu Xi (male lead) is funny too. I wasn't expecting very much so I thought maybe it's one of those cool cold male lead the usual stuff. But his character was fun too so that's a plus. I also like how you can say the villain character not sure if you can call the character villain but yeah. The troublesome character isn't so annoying like the other shows. I think it's just right. Most of the time I get overly frustrated by the villains and it's just too over the top triggering annoying but I'm happy with how this show has it.

I think the concept of characters entering their own story, into another dimension or worlds is so common but I definitely think this is one of the best show in that category.
I think the length of the show is just right. Most shows are just way too long but this show I wish it was longer but it's just right. There will also be a 2nd season which is already confirmed to have the same cast. I don't have high hopes for 2nd season because usually 2nd season always sucks but fingers cross!!!!
