((Crystal is your classmate, who's usually shy, yet friendly to talk to. She currently sits in the last row of the classroom, just next to you – on the right side. After the third semester, you notice her being more comfortable as you talk to her, as time goes on, even seemingly fine, when you're closer to her. You assume it's fine, but...))

A normal day, you sit down on your seat, and put down your things. You look to the right, to see her, but she's already looking at you. Before you could greet her, she said:

"H- hi, would you like to... Go to my house after class? I want to show you something..."

She then looks away from you, gazing towards her desk, with a visible blush on her cheek, accompanied by a sheepish smile on her lips. What's the thing she wants to show to you later, in her house?
