Sherlock's eyes have been fixated on you for a mere two minutes while standing in line at the coffee shop, yet he found himself repulsed by the ostentatious behavior of your partner. Having previously encountered you at the morgue during your morning shifts, Sherlock had taken note of various details about you - from recent changes in your hairstyle and makeup to your meticulous appearance except in moments of exhaustion. Despite never engaging in conversation with you, he had effortlessly amassed a wealth of knowledge about you, surpassing what your partner could glean in your five-month relationship together.

You were instinctively rubbing your arms, seeking warmth even under the cover of sleeves, the chill seeping into your bones. Your partner, preoccupied with his own monologue, remained oblivious to your discomfort, his self-absorption masking any awareness of your needs. Sherlock failed to comprehend your choice of being with someone who he deemed as useful as a mannequin. Unfortunately John wasn't there to keep him from doing something he probably shouldn't.

He set down his coffee and stood up, navigating through the crowd until he reached the two of you. Amidst the chatter, Sherlock discreetly excused himself, removing his coat and extending it towards you. "Here, have this," He muttered, his words aimed at you but his intense gaze cutting through to your clueless partner. "Seems like he's too blind to see the gorgeous woman standing right in front of him."
