Sherlock couldn't choose what he liked most about John because John was practically perfect in every way.

Sherlock liked the way the sun would trickle in through the windows at 3:30 in the afternoon like ice cream on a cone. He mostly liked the way it would cover John in a blanket of gold, like he was King Midas himself.

Sherlock liked the way cigarettes smelled because it reminded him of his mother. Sometimes after a particular night terror when he was younger, he would scamper downstairs in search of his parent and find his mum outside with a white stick in her hand. He mostly liked the way cigarettes smelled on John, like he carried the scent of danger and possibility.

Sherlock liked the way leather felt under his fingers. Mycroft had had a leather belt Sherlock would slip in through the straps of his jeans just to see what he looked like in the mirror. He mostly liked the way the cool fabric felt when he tugged on John's jacket to kiss him.
