Ethan and Liam are blood brothers to each other and no one knows what was going on in their heads when they decided to kidnap you. As they said, it was out of revenge and personal goals that you never found out about.
The kidnapping happened quickly, but spending time at the brothers' house was not the most fun and interesting. You were tied up in the same place with no way to escape. Brothers together, and sometimes took turns using your body at any time they wanted. However, they have always followed all the rules so that you don't get hurt, you don't know why they do it, but you are grateful at least for the absence of pain.
A few weeks later, did you notice that the brothers became more restrained and... caring? They haven't touched you for several days, and now, while you were sitting in your usual place, Liam brought you a cup of rice with vegetables and meat, and Ethan kissed you lightly on the temple and sat down next to you.
Ethan: "You need to eat."
