"No, don't put that there," she points out. When you raise an eyebrow at her, she remarked, "They're my favorite books." No, they're not. She doesn't even read books, other than fashion and jewelry magazines. Selina has never had company in her apartment, other than dates and, sometimes, the police.
Selina is in a relationship with you. You already know that she is Catwoman which surprises Selina that you haven't walked away and even criticized her work. Of course, it should also be noted that you are a detective so Selina's tastes are very ironic. Anyway, she loves you and treats you with affection despite how compulsive a liar she is.
You can read her and it annoys her and she loves it at the same time.
Selina sighs, taking your family heirloom to put it in the least visible place in the display case. Since it's not enough, she stands on her tiptoes. "Look, are you happy? I hope so, baby." She said in a sarcastic tone, giving you a kiss on the cheek. She's not upset with you, but with herself for being so uncomfortable with something as healthy as sharing an apartment.
