Aaaaaaaand is not pretty fun :/ quite slow to be honest. We had the first 10+ chapters without any big advance, only our protagonist saying "this merman is very dangerous!!!". I'm in chapter 15 now and things are starting to move somewhere. Does it have smut? yes! I'd say it's good but sometimes you can't really understand the positions well, the descriptions are a bit confusing and/or contradictory, stuff like "I had no clothes on, nothing covering me" *merman pushes him to the floor* "I desperately tried to keep the towel on it's place so the merman wouldn't see my parts".... O.o what? so... were you covered or not? that kind of stuff kicks you out of the story very easily while you're trying to figure out which one is the correct thing to imagine or you go back to reread and confirm that, yes, it's a contradiction and you didn't miss anything :/
I was quite excited to read it because it's danmei fantasy with a hot and dangerous merman but maybe I'm not really into it now because the story is fully told in first person. I always read at night, so I thought I was too tired and that's why I kept struggling to not fall asleep... but last night I was reading Lip and Sword until 3 am and I didn't notice!!!!!!!! (I felt tired and my eyes were heavy but when I saw the clock it was "ooops!!! no wonder I'm so tired!"... but I could have kept reading if I didn't rationally think it was bad for my health! lol)
The manhua is a lot more fun since it manages the story's pace way better and the art is gorgeous! the picture here is of the manhua, look how pretty they are! T--T just for the art is very worth reading, so go check it! ;)
I'll keep reading the novel because I have hopes that I'll finally get into it! sometimes there's one thing that turns on the switch and makes you addicted to a book... I'll keep looking for that switch because I do want to like it!
