Chapter 87: Status
While walking toward the restroom, Aiden thought about what had happened earlier and how he wasn't able to control himself properly. He could think straight at the time, and he just wanted to follow his instincts, and that's what he did, and doing so made him feel relieved.
Their bond had also become stronger than before with his big sis. While he may have loved her before with all his heart, he had been hiding many things from her. He now knew what it was like when someone you love with all your heart plays with your emotions.
He didn't want to think about what had happened. It felt like a nightmare to him, one he never wanted to experience again in his life. To prevent that, he had to be honest with her and love her with all his heart, not only in his mind but through actions.
