The Untouchable Ex Wife by Mizuki Sei

Chapter 1507
"What's the matter, master?" Stefan asked teasingly.
"Stop messing around. It's serious," Renee grumbled, "I was on the phone with my brother, and I told him that I found a good
helper, but he thinks you have ulterior motives and wants to interrogate you. So, you've got to talk to him nicely when you call
him later. Don't expose yourself, okay?"
Stefan frowned. "Why do you want to keep me a secret?"
"It's just better to avoid trouble. I told him long ago that I would cut myself off from you, and I've already broken my promise.
Forget about my brother being disappointed in me, I'm disappointed in myself!" Renee complained. She thought that she was
someone who always kept her word and stuck to her principles, but it seemed like she broke all her rules when it came to Stefan.
"I'm sure he can recognize my voice. How can I not expose myself?"
"Well, you can try to talk in a feminine voice, I'm sure he won't be able to tell... It's perfect since you're a helper too," Renee
suggested mischievously. She did want to fool Quinton, but she also wanted to hear Stefan talking in a feminine voice. It would
be hilarious.
"Okay." Stefan raised his brows and agreed. He took Renee's phone and called Quinton.
"Hello, you're the new helper my sister hired?" Quinton asked sternly, hoping to intimidate the helper.
"Yes." To Renee's shock, Stefan spoke normally and said," I'm Stefan."
"What? Who... are you?" Quinton was astonished.
Renee's jaw dropped, and she didn't know what to do." Stefan, what... are you doing? Didn't I ask you to use a different voice?
You..."
Nonchalantly, Stefan said, "Ren is now my responsibility. Our goals are the same regardless of our past feud-we both want to
protect Ren and make her happy. So... I hope you won't meddle too much in this." Before Quinton could say anything, Stefan
spoke first. His tone was sincere and formal, but it was undeniably very touching.
After a brief pause, Quinton asked icily, "Are you serious this time?”

"I was always serious, but many things happened in the past, and she and I always missed each other."
"Well, can you guarantee that there won't be any accidents this time?"
"There might be, but I promise you that I'll stay with Ren forever, and we'll face any obstacles together."
"You want my sister to suffer with you?" Quinton asked sharply.
