For the splitest of seconds, the corner of his lips curled upwards. Colby had a sincere look in his eyes, the slightest bit of glee that was for no one else than his darling little Yumaki now. As she moved her hair, he slowly and gracefully guided the collar across her soft little throat and the back of her neck before fastening it. There wasn't a pinpoint moment of discomfort to be had as the collar was expensive and every penny of it's price was geared toward luxury and perfection. She belonged to him now, and he felt such a rush lf happiness at his core. Such a cute and sincere little neko was all he ever needed. Now the most wonderful combo was all his own.  Where his wealth came from was rarely known, but Colby certainly made sure that the collar was nothing short of a pleasure to wear. He grew close to her and snuck a finger under her collar, hooking it and keeping her face near to his own. "Let's take our school things back to our room Yu~ I have plenty of things to show you and such precious little time." He played, now guiding her out to his fabulous campus room.
