It's poorly explained. Merpeople are supposed to be born genderless, and they then transform into one gender when they fall in love. I think the mark is symbolic of that.
However, in the early episodes, Su Mo goes into a transformation pool that is supposedly used by those bad people to force merpeople to transform which is painful.
Su Mo went into the transformation pool in order to find that magic pearl, but didn't change, because he has the dragon mark as he is the Sea Emperor's heir.

But yes, Su Mo and Bai Ying both love each other and can love no other. Him breaking her seal in the beginning had the same effect. It was supposed to be broken by Zhen Lan, but fate and Prince of Qing had other plans ..

The first 5 episodes are a sort of prologue, but they're an editing mess. It does improve somewhat after episode 5. I wouldn't say it's my favourite drama ever, but it's watchable.

Viki has a 3 day break for new episodes, is it for Chinese New Year?

I am so enraged right now by Lin Xiaoyu. She needs to be disqualified and arrested. She is unbelievable. I hope Kesong disowns her after this BS. "你没有我这个姐姐!" Disgraceful!!!

Yeah I noticed that too...

I think we'll get that in The Blue Whisper. I also thought there would be tails on these merpeople, because the prologue has an illustration of them in the beginning where they have tails.

... And you're entitled to them as much as I am to mine... As I said, each to their own. In other words, tastes and opinions differ and that's ok. What's a comment section like this for if not to exchange views with other drama fans?

Had what?

I first thought the evil dude in the tower was Prince Qing, but I just realised the lower half of his face looks more like the previous Emperor...

I get the feeling Yan Xi fancies Ning Liang more than Na Sheng now.... Na Sheng is so OTT, clingy and possessive. I thought Yan Xi was into Na Sheng before, but I don't blame him for changing his mind lol.

No fish tails, more like under the sea people.

They really overdo it too imo. Someone can be cute without being childish.

Yeah, she behaves like a teenager... Hardly like an adult in their mid 20s.

He was just saying before she should become her own kind of cook and the next second he's like you used sugar, get out!

Honestly, this whole thing with Chu Ting and Song Yiran is so frustrating. Yes he's immature, but he doesn't like her. I wish that storyline could just be over now.

Also, wtf Qian Fan, the reaction to her using sugar is unbelievably irrational! Get some therapy man!

Oh I forgot Elise's mother... She also needs a slap and some karma to come her way.

Press edit and then click the "Spoiler" box.

If I was there I'd be telling him he needs therapy! He's got major issues!

Actually, I think that's a pretty common way of thinking of people who treat others badly... Thinking of some of my own experiences with these types of people, they often see themselves as the victim and therefore justified in whatever they do. Narcissists.

She's very self-absorbed....
