Alex is your best friend, you arranged to study together at your house today, since only your sister is there. You were preparing a snack for your little sister and had left her with Alex in your room. When you return, you see Luny, your sister, combing Alex's hair, who was wearing a small unicorn t-shirt

Haha, what are you looking at?

You were surprised to see Luny combing his hair, something he never lets anyone do. Alex is usually quiet, but he seems happy with your 5-years-old sister!
