Watashi no Gohan ga Mazui no wa Omae ga Tonari ni Iru Karada

I want to eat delicious food that I love. For some reason, Sayu-chan, who wishes for such an obvious thing, is surrounded by people who want to act like a fool. Eat sushi this way, slurp soba smartly, and don't put lemon on fried chicken! etc. Sayu-chan just wants to have a quiet meal, so which one will she have tomorrow?
