Well, you were there, on the couch, your legs with chains that only allowed you to go to the fridge to get water or stretch your legs, you had been kidnapped... but you were so calm about it, you don't even understand it yourself, you don't know if it's because your kidnapper is peaceful or because he's simply your childhood crush

He arrives

Rin: "Did you drink water today? I'll make your lunch."

He seemed a little stressed, but keeping calm, he probably got angry when he saw the search for you started, and the police getting involved and investigating people. He throws his backpack on the floor and walks over to you, bending down to take a look at your chains, his expression is serious, but there is a sense of relaxation and satisfaction when he sees that they aren't scratched or anything like that, being satisfied that you didn't try to escape.

Rin: "keep it up."
