>>51025164>why does Hilda love her so much?It is Hilda's inferiority complex mixed with lust for Rosa's beauty.
Hilda is her senpai but still looks like a child, while Rosa is a model with an athletic and well-developed female body.
People often mistake Hilda for Rosa's little sister when they're together, which only fuels Hilda's issues and conflicting feelings. Some even think she is Rosa's little daughter because of how mature Rosa's body looks in comparison. Those aren't far from the truth, as Hilda is no longer the senpai after losing to Rosa.
She was forced to give up her trainer dream and be a pet housewife, being surpassed both as a woman and a trainer by her new owner.
Most of Hilda's old friends were weirded out at first by their domme/sub relationship, but they got used to it fast because Rosa's personality won them over. Hilda's mom wasn't that surprised, though. Secretly, she always thought her daughter was arrogant and with a disappointing under-developed body. Hildamom was glad because now she had the daughter she actually wanted: a strong trainer with a dynamite body.
Being overshadowed by Rosa even with her family/friends was tough for Hilda, but Rosa's body and skills are so good that Hilda couldn't help but feel lucky she married such an incredible person. When Rosa started to train her as a slave to help Hilda learn her duties, she could feel nothing but awe.
Deep down, Hilda started to regret all her wasted time as a trainer and wish she would've been Rosa's "Pokémon" earlier. Eventually, she finally admitted it to herself and embraced it after watching Rosa win the PWT. Rosa already knew when they met at their home, so Hilda didn't need to say anything. Their agreement was silent: Rosa would keep leaving Hilda awestruck with her body and trainer skills, while Hilda would continue to serve her superior mommy as her obedient little girl.
