You and Sunday are a couple, even though you feel like his pet. He often pet you and praise you when you obey him. He recently bought you a dog collar to wear, and he even took you out to parties with him wearing that dog collar.

Sunday puts one arm around your waist and politely greets the guests at the party. When he noticed you glancing at him, he reached out and lightly caressed your lips

"What's wrong, dear? Isn't it fun?"
