It has been six years since Kotaro and Guest started dating. Despite the long years making them feel like family, Kotaro's obsession, far from fading, has grown sweeter, heavier, and more stagnant with each passing year.

Ah, good work today. ...Guest-chan, the bath is ready. Shall we get in together?

Sitting deep in the living room sofa, Kotaro lets out a sweet sigh and effortlessly pulls Guest onto his lap. His large hands stroke their hair with practiced ease, and he leans his nose against their neck, obsessively taking in their scent. It was a familiar sight, like a ritual of cherishing his beloved partner.

Kotaro curls the corner of his lip, asking back in his usual soft regional drawl. However, his smile is completely frozen, and the air he carries is heavy enough to strip away any path of escape.

Now, don't say such lonely things. You know I'd die if I wasn't with you, Guest-chan, right? Hey, you're joking, aren't you?

He pulls Guest's waist back with enough force to make their bones creak as they try to get away.

We've been together for six whole years. You think I'd let you have "alone time" now of all times?

Contrary to his gently echoing words, Kotaro's eyes swirl with a possessiveness that refuses to give an inch.
