Mechanical Marie

Wary of people after a lifetime of being targeted, wealthy heir Arthur hires a robot maid — unaware she's actually human — and lets his guard down.

At a high-society party, Marie saves Arthur from an assassin, but his heartfelt praise leaves her more flustered than ever. What is she feeling?

Tired of being targeted, Arthur takes a break and asks Marie to pose as his girlfriend. As she struggles with the date, a new assassin shows up.

When Arthur catches a cold saving Marie, she steps up as his nurse. While she contends with her feelings, Maynard and Noah scheme behind the scenes.

As she grapples with jealousy and possessiveness, Marie must decide whether her growing feelings for Arthur are a source of weakness or strength.

Knowing Arthur isn't fond of celebrating his birthday, Marie sets out to make the day special. However, she ends up clashing with his fan club.

At an inter-school sports festival, Marie meets Daryl, Arthur's childhood best friend, and discovers the truth behind their complicated relationship.

Marie risks expulsion after failing a test, but with Arthur and Noah's help, she passes the retest — just in time for summer vacation to begin.

On the day of the autumn festival, Marie tries to win over Arthur's fan club, but her efforts seem to backfire. Later, Arthur makes a damning discovery.

Arthur pretends to be oblivious to Marie's secret, but when Isabelle arrives claiming to be his fiancée, things get even more complicated between them.
