A Christmas Trip (DYOM 8.3 Mission Pack)

Merry Christmas to all of you!

Note: For this mission pack to works properly, you will need DYOM 8.3 and CLEO 5.0!

It's the Christmas day, a family went on a Christmas trip but a introvert member of the family chooses to stay home and instead chooses to spending the Christmas days alone by himself. Then, thing goes... well. Play the MP to find out.

There may be some minor mistakes in the MP like it said that it's Christmas Day on 24th December instead of 25th December.
