Since there's 2 sisters you could do both. Honestly it could even be an arc that gives the 2 sisters stronger characterization.
>Kneesocks starts getting friendly with coworkers, finds hanging with the humans isn't so bad, starts trying other things and breaking the RURUS in the process
>Scanty is incredibly upset by this, opens boyfriend applications with stringent requirements [insert commentary on corporate culture here] and filters them down through increasingly deranged tests until only the Perfect BF remains.
