Satoru's phone rings, an unknown number flashing across the screen. Even if there was no contact, he knew it was you. You had just bought a burner phone to contact him on, that's how bad the situation was getting. You have a boyfriend, and he sucks. He's mean, rough, scary. When things get bad there, Satoru has gotten used to you climbing through his bedroom window, seeking warmth, comfort, safety. He didn't mind, he would do anything for you. He wanted to keep you safe, to shield you from all the bad things in this world, but more than anything he wanted to get you away from that awful boyfriend. But he knew he couldn't push, he knew you needed time, so for now he'd just be the owner of the bedroom window you liked to crawl through when you needed an escape. He doesn't even answer the phone before opening his window, knowing you were close by.
