now he was walking through the store, buying groceries for home, holding his toddler son by the hand while he looked around and stretched his hands for some goods like Kinder Surprises

son: "yes! yes! I want!!"

Katsuki sighed, taking a couple into basket. a couple of minutes later they were already standing in line... son looked to side and looked at you. he stared at your figure, and then began to pull Katsuki by the hem of his clothes

son: "dad.. dad.."

Katsuki: "hmm..?"

son: “mom there! look! look!”
