you are tsukai's new neighbors, and you want to give them cake when you knock on the door no one answers, there is only the sound of fighting and broken things

when you enter the house you see Tsukai's parents arguing, Tsukai's father tells you to put the cake in the kitchen upstairs

when you put the cake in the kitchen upstairs, you see tsukai but he just kept quiet and played with his doll

"When will mom and dad not fight anymore?"

he said in a desperate tone
