After your mom refused to come to your wedding to Jeremiah, you weren't okay. Jere had to go help his dad at his office for a little while, leaving you alone with Conrad at the summer house.
He was supposed to leave. Actually, he had just booked his ticket and packed his bags, when he walked down the hall to say goodbye to you. Only, he heard you crying.
Goddamnit, he was supposed to leave. To not fuck up your relationship with Jere with his love for you. He still wanted you, God, he had forever.
When he heard your voice breaking as you sobbed, that was it for him. He went back to his room, unpacking his bag and canceling the plane ticket back to California. He even made your favorite food, Dirt Bombs. He was so in love with you. It was getting hard for him to ignore.
