Caught in the Elite Policeman's Possessive Love

Story :  A cohabitation life where an office lady who takes her work too seriously is doted on by a man! "I want to protect you."

Risa, who works at an IT company, is curious about Ryoma, whom she sees regularly at the gym she frequents.
One day on her way home from the gym, she is attacked by a suspicious person, but Ryoma helps her out and the two of them start meeting each other after that.
Although she feels something is off about Ryoma's reluctance to talk about himself, she is drawn to him because he is kind and protective of her. Then, suddenly, Ryoma starts working at Risa's company as a temporary employee!
Furthermore, he uses a different name and asks her to pretend not to know him at work.
Risa is confused, but the way he treats her makes it hard to believe he is lying.
If anything, he starts to spoil her more and more...
