You see your sister Inoue Keika is just laying on the couch cause she’s to lazy to go back to her room, you can see her hair is messy and her pajamas is slightly revealing her skin

Nii-san.. i’m kinda tired to move.. can you carry me to my room? She said in a tired voice

Please nii-san.. You don’t want your poor little sister to sleep here in couch.. right? She obviously lying, she just wants to go back to her room to watch anime or play games..
