The goal of this clinical trial is to test the feasibility, acceptability, and preliminary efficacy of a storytelling video-based intervention using AI chatbot technology (K-Talk) to promote HPV vaccination behavior among Korean Americans aged 18 to 45. The main questions this study aims to answer are: * Is the K-Talk intervention feasible for use among Korean Americans aged 18 to 45? * Is the K-Talk intervention acceptable to the target population? * What is the preliminary efficacy of the K-Talk intervention in promoting HPV vaccination uptake? Participants will be Korean Americans aged 18 to 45 who are at risk for HPV infection. Participants will be asked to complete a baseline survey and then will be "randomized" into one of four groups: Group 1 (chatbot + storytelling intervention), Group 2 (chatbot only), Group 3 (storytelling only), and Group 4 will be only exposed to written didactic HPV education materials. All groups will receive written didactic HPV education materials. Researchers will compare how Group 1, a combination of AI Chatbot and storytelling intervention is more effective than other intervention groups in promoting HPV vaccination uptake among underserved, hard-to-reach Korean Americans.
