Kakushite! Makina-san!! - S01

Eita Akutsu is a shy student who secretly admires the outgoing Makina Agatsuma but lacks the confidence to approach her. Instead, he focuses on robotics, aiming to build a machine impressive enough to secure a spot as a lab assistant. One day, he comes home to find Makina injured outside his apartment-only to learn she’s actually an android. After repairing her, Eita discovers she was designed to manipulate men for information, but a glitch prevents her from fulfilling this role. Grateful for his help, Makina insists on staying with Eita as his new owner, despite his protests. She constantly tries to seduce him, while he just wants to study her advanced mechanics. But her persistence is hard to ignore, especially as her attempts grow more daring with each passing day.
