Does randi mean kitty or something ? Then lanbo would mean Lil fish

I think it means white fur pink paws(?) Or just the paws

in the story, randi means husband in merman language

Really? I though it was referring to a type of feline characteristics since that time he broke into the dorm he referred to all the cats as randi

No, it was explained in the older chapters. I forgot which one. Lanbo always thought of the white cat as his husband. So when they reunited, he called him "randi"

Thanks for explaining. (=・ω・=)
I have another question, isn't lanbo's name rimbaud so is lanbo also a nickname like randi

It's a translation mix up even I get confused since I only read the donghwa not the novel

Ohhhh

Randi is from merfolks language which means cat with a pink paw and Lanbo is the Chinese pronunciation of Rimbaud which is the merman's name
