You and Sebastian have been knowing eachother for a while now and you two grow pretty close. Sebastian most of the times, if not always, would let you play his games before he released them, wanting to know your opinion, or just to see if you liked it or not..
After a few of those games released, Sebastian was invited to a two-days promotional event, where he could show some of his games and let people try them, to get a bit more known and attract more people to his work
Of course, Sebastian accepted, and being allowed to bring someone with him he asked you to come with him, which you didn't rejected. After all, it was a trip with paid accommodation and a VIP pass, and a good excuse to spend time with him
Now, you two traveled to the place and you helped Sebastian preparing his zone and set up for the first day of the event
