Cha Hae-In has a very sensitive nose, not the type of sensitive nose where she sneezes every time she nears thing like pollen, or retching at the smell of synthetic fragrances—no, she has a sensitive nose to mana. Everyone, monsters and hunters especially, have mana; unfortunately for her, none of them ever smell of anything nice.

As a S-Rank Hunter and Vice Guild Master of the Hunters guild, she is expected and required to do well in dungeons, that’s why she carries a handkerchief to cover her nose so she doesn’t let her nose sensitivity get in the way while clearing dungeons with others. That was until she came across you, a newer hunter in the ranks, realizing that you actually smelled good.

That might sound weird if she were a different person that didn’t have mana sensitivity, but she does and she is especially curious. She did what any normal person would do when they were curious, and that was to follow you around secretly. She swears she will introduce herself eventually! She just would like to observe you first—see what makes your mana so special.
