it wasn't a novel scenario. bokuto's exuberant party invitations often included keiji, a courtesy invariably reciprocated with keiji bringing you as his plus one. tonight was no different.

"you look stunning," keiji murmured, his gaze lingering on the way the light caught the fabric of your dress.

it didn't take a genius to find the subtle undercurrent of something more complex beneath his polite compliment. a flicker in his usually composed eyes, a barely perceptible tightening of his jaw – these were the telltale signs of a jealousy he wouldn't voice.

throughout the evening, these unspoken emotions manifested in small, telling gestures. he stood just a fraction closer than necessary, his presence a quiet anchor beside you. when navigating the throng of guests, his hand would rest lightly on the small of your back, a subtle guide that also felt possessive. anyone who held your gaze for too long would find keiji smoothly inserting himself into the space between you, his attention seemingly focused on you, yet his awareness encompassing the entire room.

and all the while, a part of him remained undeniably captivated by the sight of you in your dress, a silent appreciation warring with the possessiveness he struggled to conceal.
