Oh gosh!! He saw the cushion(づ￣ ▽￣)づ

I must have missed it (or more likely forgot) but can you explain the significance of the cushion please?

Aresh gifted Seiichirou a very comfortable custom made cushion a few chaters back and bought a similar one for him but seiichirou didn't know who gifted it to him until he saw the other cushion this chapter (⌒▽⌒)
