I recommend 'The Handsome Supporting Female Character After the Book' to you. The female protagonist, Bai Yixi, had transmigrated to become a female supporting character in a novel. When she was young, she had bullied the male protagonist. However, after she returned to reality, she went to high school, and the male protagonist also went to the same school. The male protagonist suggested that the atmosphere detector could detect people's hearts and guide the female protagonist to recognize her inner feelings. The two of them finally got together. The male protagonist was jealous when he saw the female protagonist wearing a swimsuit and taking photos with someone else. He scolded the female protagonist, but later, the two of them made progress in their relationship. I hope you like my recommendation, Mwah ~😗
