Listen To Your Heart

You know I had to. I had to, right?

HEADCANON TIME:
John's heart is your typical Big Guy goober. He's had his share of breaking, but nothing severe, as evident in his size and the deep red colors of his clothes. He's kind, but also very tough.

Meanwhile, Sherlock's heart is colder and more frail. He's even thinner than the man himself, in that regard. His lack of any distinct heart clothing or colors indicate that he's ignored most of the time, which has made him put up a very bitter front.

So of course, when Sherlock's heart IS noticed, and if he feels somewhat similar to that person, he starts beating rapidly. Which Sherlock duly notes

Also, not gonna lie, but I'm really proud of Sherlock's expressions, OOC as they may seem
