He's Pretending to Be a Good Little Wolfdog, Sister, Don't Even Think About Escaping Tonight

My best friend went abroad, and I was forced to take in her 22-year-old brother who was the school idol. I thought it was just an extra burden, but I didn't know that he could go to the hall and the kitchen, and even call her "sister" with red ears. I relented and doted on him as my younger brother. Until that dinner party, he drank the wine with some spices for me. When I got home, the usually clean and pure boy had red eyes and hot breath on my neck. He prayed hoarsely: "Sister, I feel so uncomfortable, help me..." I lost control all night, and I just thought it was an accident. But he got even worse, being clingy and coquettish during the day and secretly exercising his abdominal muscles at night. It wasn't until I attended his graduation ceremony that I saw the mysterious CEO on stage who was called the "new god of the technology industry" with a face exactly like my "good brother"! He holds all the lifeblood of my company, but in front of the global media, he shouted to me from a distance: "Nuan Nuan, I, my company, and I are your betrothal gift."
