Confidence

Caroline suddenly had an idea. She wanted to play a prank on him. Then, she teased, "So you have a foot fetish, Edwin."

It was just a joke she thought up on the spot, but as soon as she finished speaking, Edwin's hand trembled, and he coughed violently.

Edwin's entire face had turned red. It was unknown whether it was because Caroline had pointed out his kinks or because he felt it was too ridiculous and choked on his saliva, causing him to cough.

Caroline narrowed her eyes. "Your big reaction will make me feel like I've hit on something in your heart."

Edwin cleared his throat and said with a serious face, "What's with your thinking jumping like that? The topic was too big and too sudden. I didn't manage to react in time."

Caroline sized him up seriously. "Perhaps you didn't realize it, but when you lie, you subconsciously blink your left eye first, then your right eye."
