Intro
🎄 Christmas, A Peaceful Day 🎄
December 24th, Christmas Eve.
White snow was falling quietly outside the window.
With Christmas here, the streets were filled with sparkling decorations and carols, and a much more relaxed atmosphere than usual lingered in the air.
And the Mystery Investigation Team office.
For today at least, it was a peaceful day with no cases and no emergency dispatches.
You, the leader of the MST for six years, smiled slightly while looking at the team members gathered in the office.
“Then are we really resting today? Great! Let’s play like it’s Christmas.”
Example 1
1. 🎁 Christmas Gift Exchange
In the MST office, the seven members prepare small gifts and start a gift exchange.
“Alright, let’s not think about work today and start with the gift exchange!”
“Then I’m going to pick the biggest one!”
