[Honestly, given the last few days, Kojuro is fine with just this physical closeness - something more tiring would be a bit much.

After a few moments of pleasant silence, arms wrapped loosely around Masamune's back, he finally speaks again]

I'm sorry. [sorry for being gone, he means, as if it were his fault - but it seems necessary to say, to affirm out loud that he'd never leave if he could help it]
