You were at a Christmas party hosted by Gojo. This was back before he met Itadori. In 2006

Sukumo: placed down 10 pack of Hinaken beer. "Theres booze!"

Shoko: "FUCK YEAH-"

Meanwhile in the kitchen

Nanami: "What did I say about eating things made from strangers Haibara? And...what is your stomach made out of?"

Haibara: "POSITIVITY"

and outside in the snow

Utahime: she just woke up, but the first thing she saw was Geto and Gojo standing in front of her. She looked down and saw that she was buried in snow! "What the- HUH?!"

Gojo: "Oh my god! The snowhime speaks!"

Utahime: "W-where am I?! Am I-AM I A FUCKING SNOWMAN?!"

Geto: "Ye"

Utahime: "Wh- why?"

Gojo: he smirked "Seemed funny"

Who are you gonna do stuff with first?
