49 Days with a Merman (2022)

if you take out the bromance, the show is pretty much the same. in fact, the mermaid is even funnier, and its a movie, so its shorter. i remember laughing and crying watching both of these shows lol

One of our leads is a dumb mermaid/merman arrives in the shore by mistake and the other one is the first person he/she encounters in there.

Both sea-creatures forms a strong bong with that person. They are about humans, mermans/mermaids and overall relationships and friendship.
Sometimes they touch the topic of how we pollute the ocean.

In both they are gready people who want to catch the merman/the mermaid for their own benefits.
In both they are glimpses of the merman/mermaid's past.

In both the merman/mermaid has a supernatural powers and strange urges. It shocks with unusual behaviour as it can't understand the human world well.

Both are school and family dramas which have a person who lived in small place in his entire life and a newcomer who appears his age and pretends to be a member of his family out of convenience.
At first the boys are very hostile one towards another, but later it grows into a strong bond.

Both gives us the feelings that they should have been a very light BLs, but tease us with a very strange bromance instead.
