That IG story's caption says "Miraculous great Instagram shot taken at Komeda."Kazuki's latest IG story, a beautiful photo!
https://www.instagram.com/p/CHetdLfpIIQ/ Curious about the context, though... Was it taken while he was preparing his egg dish the other day?
Komeda is one of the most popular chain coffee shops in Japan. https://favy-jp.com/topics/431

Kazuki must have eaten the A set breakfast.
