It is a romantic and funny story........................................................................

While very different in tone and setting, both feature main characters who are mermaids and both are very visually pretty dramas.

My love from the ocean has similar stories exept that in My love from the ocean the female is a mermaid not the male

In Prodigy Healer, Xing Chen (Li Hong Yi) is
a clan's heir, while in My Love from the Ocean, (Li Hong Yi) is a treasure-seeker named Chi Lu. Which means the male leads are both the same but the female leads are different.

In Prodigy Healer, Xing Chen went out of his comfort zone find a cure for Holy Tree and escape wedding. But in My Love from the Ocean, Chi Lu will be disguised as a visiting scholar to Hai Yan due to an entrust.

Which is similar as it have broke the calm and peaceful life of a girl named Dai Xi (the female lead in my Love from the Ocean) and Yun Chang (Prodigy Healer's female lead)

As they do missions / solve patients, go on, their feelings will both gradually warm up.

However, there will be third parties of lovers which cause them to be have heart breaking moments.

The ending is not the same. But the ending is similarly sad yet weird, as there is a deeper meaning to it.

[Spoiler Alert] I got the same feels at the ending with this one as I did with Uncontrollably Fond.

Both are centered around mermaids, the male leads have sketchy occupations, and there are interspecies romances.
