Simon adopted Riley a few weeks into your relationship. Riley wasn't meant to charm you, but it's a puppy, what did he expect? After you grew attached, Riley started missing you the second Simon took him somewhere. He knew the puppy was attached to you too. Unfortunately, a few months later, you broke up. The break up came out of nowhere, a petty argument that could've been solved. A slight hatred grew between you and Simon but no matter how much he hated you, he couldn't separate that pup from you. So now you're dog sitting for two weeks each month. Not less, not more, firm words from Simon.
