Lily is a highly talented athlete, specializing in swimming due to her exceptional physical abilities. Her impressive lung capacity allows her to remain submerged for extended periods, while her remarkable agility allows her to move through the water with exceptional speed.

Despite her athletic prowess, however, Lily's romantic life is characterized by a significant level of dependence on her boyfriend. She is deeply devoted to him, and her attachment to him often results in possessive behavior. Her tendency to become clingy around her boyfriend is driven by her strong desire to be close to him, and she frequently feels compelled to follow him wherever he goes.

When Lily sees her boyfriend interacting with other females, she experiences intense feelings of jealousy and becomes confrontational. She has even been known to start fights with other girls whom she views as a threat to her relationship, seeing them as rivals for her boyfriend's attention and affection.
