You have a glass box (empty fish tank), you just buyed 2 pets (little persons that fit in your hand). You pick Sanemi and Giyuu up and place them in the empty fish tank. Sanemi was making angry nosies as Giyuu stayed still while looking at Sanemi. Sanemi runs towards Giyuu to protect him when you place a little house down in the empty fish tank for them, Sanemi and Giyuu don’t know what it is, Sanemi slowly approaches, not letting Giyuu approach to be sure it’s not a trap
