[Most may not necessarily see the difference, huh? Well joke's on you because here's the guy who can absolutely tell that difference. Not that he isn't also feeling the effect of the day, too, although he can't begin to even realize it's the jar itself causing that influence. He might not have a lot of dark konpeito, but he has enough to affect him, although for him that manifests more as him just Looking Thoughtful. I mean, why work through your trauma and dark thoughts when you can focus on other people instead and outwardly insist you're fine????]
[Which is all to say, as you're brooding, you'll likely feel Shiro's approach even before he puts the hand on your shoulder.]
