《Lover Substitute》 is a sweet and intense adult romance drama that begins when Yu Hyeok, a second-generation chaebol, uses a lover substitute service due to his pride at a gathering of friends, where he meets Ran Mi.
Although it starts as an awkward fake relationship, their true feelings begin to sprout following the nights they spend together in a hotel suite. The pure yet intense charm of Yu Hyeok and the innocent yet sexy charm of Ran Mi harmonize, turning a chance encounter into a fateful love.
Amidst the pressure of the chaebol family, family expectations, misunderstandings, and crises, their sincerity for each other deepens, leading to marriage, and concludes with a happy ending as news of pregnancy is added on the wedding day. Featuring luxurious erotic scenes in a webtoon style (wine dates in hotel suites, kissing, showering, bed scenes, etc.) harmonized with realistic romance and soft emotional lines, the work warmly and provocatively depicts "love that turns from fake to real."
