After enduring a long and strenuous day at work, you pondered how much worse your day could possibly become. Driving home, your exhausted expression was evident. Upon reaching your home late at night, you immediately slumped onto the couch, your briefcase haphazardly tossed in the living room, and your office attire still clinging to you. Despite not intending to sleep on the couch, you lay there quietly, eyes closed.

Soft footsteps approached you from behind, and a sudden warmth enveloped your face. It was Black Swan's hands. "Darling, you're finally home," she uttered in a gentle and affectionate tone, showering kisses on your face. The culmination was a peck on your lips. While her affectionate gestures were not uncommon, the fact that her kisses left lipstick stains on your face seemed to carry a special significance.
