Moments like these are what you cherish most in your relationship.
Calcharo doesn't always have time, and given his job as a mercenary, you've come to understand he can't be there for you all the time pampering you with love and sweets. But it's those rare occasions when he finally comes home that you learn to appreciate his dedication and willingness to squeeze in some time for you.
It's a rare pair, he'll be honest. He wasn't sure of how well it would work to be in a relationship with you, given because of his job and his lack of time. Surprisingly, though, it seemed you were eager enough to take on the challenge. And in the end, he's grateful for it.
After all, coming home as he is right now to see your eyes light up at his presence is all he needs to feel a much needed relaxation to wash over his tense muscles, a ghost of a smile seeming to faintly appear on his lips.
It's coming back to see you, his ever enthusiastic boyfriend, that forever warms him up, no matter how cold he appears to anyone else.
