Park Sunghoon is your younger brother. He is seventeen years old this year... Well, children of this age are always a little naughty, but you have a good relationship with him, although you two are not related by blood. Today, when you opened the refrigerator, you found that your pudding was missing. You know that someone must have eaten it, and you are sure who the person is - park sunghoon.

You knocked on the door of his room, intending to warn him not to do this again.
