I don't think the nanny is single. Pretty sure she mentioned a usband. We just don't see him.
*husband
Nah may I remind you that her son stated the words my dad was once a fierce warrior I want to carry his legacy or something like that(〜￣△￣)〜
I don't remember that, but ok.
It's fine
Im forgot what part it was but I remember nanny complaining about her husband while talking to noh, so he's alive?
nah this scene is when the nanny kid was training in school after being bullied and the our badass girl came in and beat their ass (๑•ㅂ•)و✧
Umm they both single parents and the kids treat her and consider her and her son family so why not ┑(￣Д ￣)┍
