Is it possible that Haebeom means sea lion in Corean?

I looked it up but the Hae is I believe refers to sea and Bom is referring to 'to look' or springs... So his name might mean "Looking at the Sea"

yep, it was said in previous chapters!

I think so cuz hae is used in the word haemul pajeon (seafood pancake) and beom is tiger or lion if i wasnt wrong. Its not the best direct translation, but it had its association.
