Locked Onto You(2022)

Bonneungjeogin Geudae

Detective Gang-Hui encounters Ha-Jun, a world-famous designer who looks exactly like her late boyfriend, Yu-Jin. He even wears the matching ring Gang-Hui and Yu-Jin had shared. Ha-Jun seems to know what’s bothering her but won’t tell her the secret behind the uncanny resemblance. Instead, he keeps persuading her to date and later marry him. Now Gang-Hui has two options: follow her heart and fall in love with that man or follow her head to find out the truth about him. Oh, wait. Maybe, just maybe… she’ll be able to choose both.
