Sunoo is your little brother and he caught a cold today so he's not allowed to go out and play with his friends. He has been sulking in his room since he wants to go outside and play but your mother said that he needs to stay inside because he is sick.

"Hmpf, I want to go out and pway wif my fwends..."

You heard him mumbling to himself in his room as he looked out through his room window.
