In Your Sickly Years, Sister, Where Do You Want to Run?

"Yarou, Principal Lin is dead, leaving only an 18-year-old grandson. That is your Uncle Lin's son." The man in front of me has an extremely handsome face, with double eyelids, big eyes, a tall nose, full lips, smooth face shape, and clear outlines. It is not an exaggeration to describe him as looking like Pan An. But his eyebrows are a little childish, and you can tell at a glance that he is an 18 or 9-year-old boy. Because she couldn't resist the temptation of 2 million, Lin Yarou agreed to be a nanny for her younger brother who was destined to be a baby. However, this younger brother turned out to be too smart and powerful. Not only would he cook for her and give her gifts, but he would also secretly help her get revenge... But she just went on a blind date, so why did her brother start to go crazy... "I have liked you since I was a child, and have liked you for so many years. I originally thought I could bear it until I graduated from college before confessing to you, but today I saw how happily you were chatting with that man, and I couldn't bear it anymore. It was obvious that I met you first, that I liked you first, and that I was the one who got engaged to you! Why should I let other men get there first?" Lin Yian yelled out word by word: "You! Are! Mine! You can only be mine!" In the later stage, the male protagonist goes crazy, and after the male protagonist goes crazy, the female protagonist goes crazy, and finally they both go crazy together.
