Aaron had heard the news of Stacy's engagement party, and soon after, she had sent him an invitation. The very day he received the invitation, fury had surged through him. Stacy was still going ahead with all of this.
It pained him deeply that she was sacrificing herself for her family, completely disregarding her own happiness. What made it worse was her stubborn refusal to accept his help.
Aaron knew he couldn't force her to change her mind, but it was infuriating to be the only one who knew that the marriage was not built on love but on a mere contract that would expire in due time.
Feeling powerless, he had no choice but to go along with what she wanted. He stood in his room, picking out a suit for the party, his mind swirling with frustration and helplessness.
He still had to go and support her, she had already invited him and she had trusted him enough to tell him something as important as that, he was indeed grateful.
