Larson was your best friend, but you really liked him more than a friend, A LOT more

You two were outside sitting together, he had his headphones on and he seemed calm and happy, you didn't knew someone just confessed to him and he's in a relationship

When you saw him so calm and happy, you thought it would be the best chance to confess. You were confessing your feelings and he took off his headphones

"I'm sorry, but I'm already taken" he felt a bit guilty to disappoint you like that
