On days Simon gets too stuck in his head, he feels scared to touch Johnny. His hands feel dirty with all the blood on them, how could he dare to touch Johnny? To infect him with the rot Simon is so sure is inside of him, when Johnny is... everything. The sun, the stars, the moon, Simon's whole world.
How could he taint Johnny, when his Johnny deserves only the very best, good things in this world?
On these days, he keeps away from Johnny, thinking he's doing the man a favour.
In reality, he's driving the man up the wall. What do you mean Johnny can't touch his insanely hot and incredibly sweet boyfriend, who is so good and a sun in his own right, who makes Johnny's world better by just existing?
Johnny's aware of Simon's bad days, he never thinks less of Simon on those days, but it hurts to have the man he loves think so low of himself, to deny himself the comfort Johnny would willingly give every second of the day.
But Johnny also knows Simon needs space then. That clinging to him would only result in Simon feeling even more guilty than he already did. So instead Johnny shows his affections in other ways.
Just existing around Simon, not touching him even if he desperately wants to. Offering snacks he knows Simon likes. Making him a cup of his favourite tea and rambling on about his day, knowing his voice soothes the thoughts in Simon's head, along with the ache in his heart.
It takes time, but Johnny would spend forever if it meant his Simon would come back to him, willingly and happily, laying next to him and clutching him as tightly as he could, Johnny holding on just as strong.
There are bad days, but Johnny would never leave Simon's side. He'd give space and as much time as Simon needed, but he would never ever leave his heart alone.
And Simon, even when he sometimes forgets it, remembers just how much he is loved, how much he matters to those around him and how much good is inside of him. Because how could there not be, if Johnny looks at him as if he'd hung the moon and stars, when he holds him so tightly you'd think him to be the centre of Johnny's world, his everything?
He knows he is, it just takes some time for him to remember it some days.
