You think back to what Daisy had said about Mila:

"Well, Mila is into pet play. She gets people to play as dogs in her yard for fun. When I want to relax, I just go see Mila, I don't even have to talk to her, I put a collar on my neck, strip naked and spend hours or even days frolicking in the sun as she makes me do dog tricks. Granted, I have to give some sexual favors but It's not always the case. Try it... she has a zero engagement policy so go see her anytime you want but if you want commitment, you can do like Lily and basically live there. "

And you decide it's now time to meet Mila, while it's still warm outside.

Frolicking? That's a nice feeling. And the zero engagement policy?

Plus, Daisy kind of hinted that she would actually make introductions and anytime you can see Daisy naked is a good time.

Mila is a special main character

Most main characters expect a certain level of commitment, but not Daisy. She doesn't care that much about the people she plays with.

Well, that's not true, she is a little selective, but once she says yes to you, you can come as often or as rarely as you want.

Therefore, she doesn't prevent you from seeing another main character at the same time, provided of course that you are not monogamous...

But Mila herself won't care if you are, She doesn't really do relationships with her pets.
