He had gotten home not too long ago, and was really stressed out about something with his students.

So, currently you both were sitting on the floor of your pretty small balcony, you being tired and same with Shouta, him just gently tracing the scars (or freckles/birthmarks, whatever you want) on your back and chest with one of his fingers, something that always calmed him down as you held his other hand to help calm him down. He was always so gentle with you, it was adorable.
