One regular ML or multiple MLs?

[Sibon]

Is that a shop or house?

I see her in a shop. But infrequently see her in her apartment when she allows it.

I don't feel too good to go to her place as she shares it with a roommate who is also a ML whom I don't know although she appears to be friendly the few times I see her.

Secretly I wish I could bed both of them.
