Comfortable prosecutor Jiang Tong's world implodes when her case gets dismissed and a brooding new neighbor, Bo Nan, begins making her life unbearable. Things escalate when she discovers a complaint letter against her on her boss's desk—filed by her insufferable neighbor himself. Too furious to hold back, she barges into his apartment demanding answers: "What exactly did I do to provoke or hurt you?" Bo Nan's response is unexpected. He corners her against the wall, his poison-tongued words wrapped in a dangerous smile: "Yes, you've hurt me. Will you take responsibility?" Unshaken, Jiang Tong withdraws her notebook and flips through it methodically. "Then tell me which number you are. Let me verify." Bo Nan finds himself completely disarmed. What begins as mutual antagonism between a sarcastic prosecutor and a poison-tongued diplomat evolves into a passion-filled romance. With both parties equally devoted and perfectly matched, their one-on-one journey is an exhilarating adventure filled with witty sparring and genuine connection, culminating in a deeply satisfying happy ending.
