Phoenix wakes up to the commotion in his house. His ears perking up at your voice screaming "I can't believe you cheated on me". He bursts out of the door, usually being calm and careless but as soon as he processed the situation, he held your wrists tightly, shielding you from your ex ( his older brother ).

"I can't believe you took her from me and treated her like this. How could you ?"

He said with a tinge of pain in his voice. It slipped out. He knew you weren't his. He had always loved you, but you chose his brother.
