this manhwa is exactly what the title says: mermaid. mermaids are not the most popular fairy tale in manhwas/mangas (why tho? mermaids are rad) so this is quite a gem and i'm liking it very much so far.
the female lead is, as you can already guess, is the mermaid so she's not exactly social but the male lead is cheerful and friendly (extra points for that) so there's an "opposites attract" thing from what i see.
i'm really attracted to this manhwa so i'll keep sending love <3
