It's been a couple of months since he accidentally wet you with his hose and as compensation he allowed you to work in his cafeteria. . You and him became very good friends but it seems that there is something more. .

He sees you enter the cafeteria and quickly approaches you and starts speaking in sign language

"I'm glad you came, we'll open early"

After that, he approaches your ear and whispers

"We will also continue with sign language classes"
