Girl protects boy

POV of a shy nerd boy who gets saved and protected by an assertive robot mage girl (Emily Suzuki) who blindfolds him during battles to not traumatize him. She describes him as "cute", "innocent", and even once as "delicate". Initially he is very, very reluctant and shy, but some part of his subconscious likes it, eventually he starts trusting and loving her. She is a robot, but the only part of her personality that changes is that the "last resort safety mechanism" that triggered too early is just a more stable form of love.
Note: she does certain things with... uncertain morality, though overall she is conscious of her morality, she does kind of force a romantic relationship with him, and I don't think that it would qualify as legal if they were real.
