This question involved many different types of online novels and storylines, but generally speaking, the female lead would like to tease her male lead for the following reasons: 1. Complementing personalities: The male protagonist is usually more powerful and confident than the female protagonist, while the female protagonist is more gentle and fragile. This kind of complementary personality could make the female lead closer to the male lead and feel his care and care, thus making it easier for her to develop feelings. 2. Accidental Encounter: The male protagonist usually appears when the female protagonist is least expecting it, such as accidental encounter, accidental injury, etc. This kind of unexpected encounter could make the female lead more curious and excited, and thus make it easier for her to have a good impression of the male lead. 3. Teasing humor: The male protagonist usually uses teasing to show his sense of humor and personality to make the female protagonist feel happy and relaxed. This kind of humor could make the female lead like the male lead even more and might even unconsciously develop a good impression of him. 4. Character charm: The male lead may have his own unique charm and characteristics such as intelligence, wit, humor, etc. These characteristics could make the female protagonist feel good and more easily attracted to the male protagonist. It should be noted that not all female leads will like the male lead who likes to tease her. It depends on the story and character setting. Some female leads might be more mature and rational, and would not be easily moved by the male lead's teasing.
