Semi didn't know them all, but everyone had to have a story and some were bound to be more tragic than others if you just thought of the invitations themselves. They offered an escape and it couldn't have been as trivial as not really wanting to get a real job for everyone who came here. The reasoning people had for coming here was personal enough not to prod anyone for the why. If that information was offered to him, that was fine and the person felt comfortable enough to tell him. If not, well, they had reasons for that too.
On another side of it, when there were people who had such heavy losses and big things going on, his reasoning seemed pretty ridiculous for taking off from home, but that came back to the one person's low not being another's which just was how it was.
He should have been paying more attention, but there was no harm done. "Mhmm, it's been quiet so I had a minute," Semi nodded over to where he leaned his guitar. It was nothing special, one he scraped up money for before his parents bought him one for graduation. "It's honestly like that a lot from what I've been told so it's pretty chill working here so far."
Watching Mafuyu kneel down to open the case, he grinned some when the guitar was offered to him. "No big deal, I'll get you fixed up. Semi took the guitar carefully, giving it an appreciative look over as he pulled over a stool from behind the counter, settling onto it with it in his lap. "You just start playing?" He questioned, though the quality of the guitar on his lap suggested otherwise. He didn't want to make too many assumptions, it just wasn't in good style or tact.
Carefully slipping the new string into place, Semi tightening the peg, strumming his thumb over the strings before plucking at each one individually as he tuned them up. "Shouldn't be more than a few minutes. Here look..."
And he nodded the other boy over, taking a minute to tell which each string was as long as Mafuyu wanted to listen to him, grinning some more as he took another good look over the guitar before handing it back. He'd love to play it and maybe with luck sometime he could. Instruments were personal. You either got the offer or you were comfortable enough to ask. Someday.
"If you need anything else, bring it on back to me. If I can't fix it, I'm sure my boss can."
