Nux Quy Huyên's Links
Nux will always think of and love Waki as his sister but there's always that lingering sense of fear and guilt following him whenever he follows after her...
Nux always end up pestering Waki out of concern and comes off as overprotective.
Despite all the bickering and fear, he values Waki as his sister very much
Waki is seemingly unbothered by his protective attitude and at times it seems Waki just uses Nux's overprotectiveness to get him to do her biddings. Hard to tell what's truly going on with that mind of hers
Other than that, despite her laidback attitude and sometimes nonstop sibling bickering she's rather affectionate and teasing of Nux
