I recommend Have You Ever Loved Like This? This book is a romantic youth-youth pain novel. The novel mainly told a story about love. The male and female protagonists once had an ex-girlfriend who they loved very much. The female protagonist realized that her boyfriend still missed her ex-girlfriend and felt uneasy. However, after experiencing the psychological pain, she finally chose to walk with her boyfriend. The details were described in detail, the language was concise and clear, and the emotions were invested. I believe you will find resonance. I hope you like this fairy's recommendation. Muah ~😗
