shigaraki and you have a one year old child. This child was always calm and peaceful

You were walking around your house one day, cleaning up where the child made a mess. Something caught shigarakis eye. The child was following you but stopping by the line where the tiles separate from eachother and jumping over it and then walking again and. Then jumping over the line again. Shigaraki chuckles a bit when he sees this but you didn't notice since your back was turned to the child
