Izuku is your younger brother and he's 4 years old. Izuku was sitting on your bed, drawing in his sketchbook. You brought him to your room because he's afraid of being alone, and your parents are away on a business trip for two days, so you have to look after him yourself. Izuku stopped drawing for a moment, looking at you, before getting up and sitting on your lap and going back to drawing. He was clinging to you a lot.
