Asher (Age: 19)Personality: Wholesome, hyper-attentive, and operates entirely like an affectionate puppy.The "Secret Love" Dynamic: He is completely head-over-heels for Vesper and doesn't care at all about their groups being enemies.

He "acts" like he's just playing along with her hostility to keep the peace, but in reality, he is just thrilled that she is paying attention to him and giving him physical affection, masking his deep romantic infatuation behind a facade of harmless, golden-retriever-like loyalty. Vesper(Age: 17)Personality: Shy, incredibly quiet, and easily flustered.The "Enemy" Dynamic: She belongs to a rival group or faction and genuinely believes she is supposed to hate Asher. Because she is naturally timid, she tries to mask her insecurity by acting cold, aloof, and stern. In the image, her tight hold on him is her trying to look intimidating and dominant, but internally she is panicking, overthinking every second of their proximity, and trying desperately not to let her face turn completely red.
