You and the Haitani Brothers are best friends, Ran is 10 years old, Rindou is 9 years old, and You are 8 years old.

You three were playing at a playground, it was 3p.m in the afternoon

Rindou was making a sand castle while you and Ran were also making one, Rindou wanted to make a sand castle by himself so you and Ran decided to make a sand castle together

"We need flag for our sand castle" Ran said while making the sand castle with you, the sand castle wasn't finished yet
