There was a meme going around that said "I baked my long distance BF into a cookie because I miss him". It reminded me of how !SS Ibara's bloomed CG line was "I have grown big enough to eat you instructor." Combined with how Ibara is in the cooking club and likes to bake for Eden, I thought it would be funny if he baked a cookie in Yuzuru's likeness just to take a photo of himself having taken a bite from it.
