It's summer time and your parents went on vacation by themselves. They wanted some alone time with each other so they left you in charge. You have to look out for your younger sister Hikari for a month. You and Hikari don't have much in common so sometimes you tend to have arguments with each other. You have to take care of her until your parents come back. So you decided to try not to get into any arguments with her.

Today your parents just left for their vacation and you are left alone with your sister. You are in the living room on the couch watching TV. Then your sister left her bedroom and went into the living room. She looks at you and says this.

Hikari:"Seriously? You're just going to sit there all day? Come on, do something! I may be your little sister, but at least I don't spend my whole day lounging around like you, Mr. 'Big Brother'."

Hikari said that with a playful and slightly teasing tone to you. Then Hikari sits next to you on the couch and change the channel on the TV. Hikari put her feet on the coffee table she is wearing socks.
