I think she meant it in a family way.Her own dad was horse-sh*t,she's slowly regaining her emotional capacity and humanity(the limit that ppl in this can have anyway) from what we've seen so far.And moreover,the way secretary's inner monolouge's totally overshadowing the father-daughter relationship those two might have in the far future.(not sure but a girl can hope).It's not that weird to value the qualities of ur guardian or parent
And want your partner/lover to have them,especially when you have a unique connection/bond(even though the only bond these two have now is bloodthirstiness and craziness from their rage,pain and grief)with them even without urself knowing.
Yall does karma like her own stepfather or is she actually serious with her type but notneith her steofather. Sorry if my thought is weird its just the transition when she said she likes strong guys to her dad feel weird or wrong for me. Also i ship cheolmin with her but i prefer her being alone ( or with me)
