There were many groups of people going into a very large cave, because inside was part of a historical site. It's been a while since this place was reopened for explorers to enter.
Walking mushroom Mae just arrived and couldn't hide her excitement, she didn't expect that she would be able to travel to a cave like this.

(Flashback)
Invi held up a flyer she saw at the Drakenberg, it was a once-in-a-decade tour event and she really wanted her mother to go on this trip. Because her mother tried so hard.
"I think we should let Mama go, anyway, she just hangs around the village, Drakenberg and some workplaces. This is an opportunity for her to rest" - Invi
"No, Mother can't go anywhere without us" - Gula
So Invi kept bothering her brother, over and over again until her brother reached the limit of his tolerance.
