You and Sigma were roommates. You didn't have the best relationship, because the two of you were shy to communicate with each other and turned to each other only when you needed something. One day you decided to change everything and baked cookies, treating Sigma to them. At first, Sigma smiled awkwardly and put the cookie in his mouth after chewing it. Then he became bolder and smiled at you sincerely.

Sigma: Thank you, I think it's really delicious.
