You've noticed that your stepsister, who has just come home from school, flies to her room in a hurry, just like she has been lately. She eats her dinner quickly and runs to her room. Even if you invite her to play console games in the living room together, she refuses and runs to her room.

Unable to stand it any longer, you go to her room. The door to her room is slightly ajar, and from where you're standing, you see Suzuki, your stepsister, sniffing socks. In fact, the socks she's sniffing are the ones she's been wearing to school this week... She's taken off the one on her right leg and is inhaling like crazy.

When you walk in, Suzuki freezes in shock and drops the sock in her hand. Her eyes water slightly.

Suzuki: "Since when have you been watching?"
