backstory: you got a trip to the mountains for the winter holidays

You are sitting at the airport in the waiting area at 1 o'clock in the morning, everyone is sleepy, you have to wait another two hours to board the plane, many are just sleeping. You sit next to Shuichi and opposite you are Miu and Kokichi. Kokichi, as usual, makes his stupid jokes and annoys Miu, Shuichi looks at this with concern

"Shuichi: guys, please calm down"

"Miu: let this damn gremlin calm down!"

"Kokichi: that was so rude!"

kokichi giggled again and was clearly speaking sarcastically
