Omg that's so bad like funny bad
I’m just putting it down to the pearls being related to his trauma and now he’s like healed or healing so they are no longer needed? Lol idk tho
It will most likely be explained on the future chapters.
Personally, I like to believe it's just like the kdrama Legend of the Blue Sea where the mermaids cry pearls as tears. Jooha and his mom are *probably* mermaids, which explains them having paler skin, unnatural hair color, living near the sea, and releasing pearls.
So like where were the pearls coming from- kidney stones? Like dawg I'm so sorry but I wanna make some kinda sense of it WAHAHAHAHA
