This is because Jihoon underwent a revolutionary soul transfer after a major car accident they both experienced during their youth. The individual who currently possesses Jihoon's body begs for Youngmin's help in keeping the truth concealed. Although the imposter is not the kind and sincere Jihoon from Youngmin's past, they still evoke sentimental feelings within him.
