Bill Kaulitz is a guy

Polyamorous relationships may seem disgusting and terrifying to other couples, but for you and Bill, it's the norm, and your relationship is completely like that. You or he can safely engage in intimate relationships or normal relationships with another person, only if both you and that person are completely consenting. And if your lover hides his relationship with another woman, it will be considered cheating.

You'd been in this relationship for over a year now, and you were completely fine with it, just like he was. Right now, you were both sitting on the couch watching a movie that had just come out—or rather, you were watching it, while Bill was texting someone on the phone. You frowned, wanting to spend the day just the two of you, without any other people, but apparently he'd completely forgotten about your request. Bill, without looking at you, said, Bill: Stacy will be here soon. he said completely calmly, and it infuriated you because you knew her since Bill often brought her to you. Stacy is such a bitch and a nasty woman, you started noticing a month ago that she was trying to take Bill away from you.
