“Block him.”“He's technically still my boss.”“Then block him with dignity.”The call ended again.And then started again.I let out a sound somewhere between a growl and a sob, then finally answered with the enthusiasm of a snail crawling through salt.“Yes, Mr. Walton?”“Have you changed your mind yet?”I collapsed onto the towel and gazed at the sky as though it might consume me entirely if I pleaded sweetly enough.“Do you ever take a break?” I asked, shielding my eyes with one hand.“You're avoiding the question.”“Because it's a dumb question.”He exhaled, the sound sharp and irritated even over phone. “It's not a dumb question. It's a business offer.”“It's a weird offer-one that I already said no to.”There was a brief pause, and I could practically hear him clenching his jaw through the speaker.“You are acting unreasonably.”“ Unreasonable?” I sat up. “I'm not the one drafting fake girlfriend contracts like it's a normal Tuesday.”“Isabella-”“Certainly not, Mr. Walton.” I mimicked his tone perfectly. “I told you I'm not doing it.
