Let Me Be Your Knight (2021)

Similars

Pontifex Rembrary, a character known for his divine powers, gets transported to a new world while fighting a devil. He possesses the body of Woo Yeon Woo, a member of an unpopular idol group, and helps turn the group's fortunes around after a disastrous live performance. With his charisma and divine powers, he becomes popular among fans but faces challenges from his past, contending with strange religious groups and the devil.
Similarities: - Both involve the entertainment industry. - Enemies-to-lovers vibes. - MLs are both the famous - FLs are both the non-famous half of the couple. Differences: - FL in SS works directly with the ML in the industry within the PR team whereas in LMBYK FL finds her self working with ML due to a coincidence and her circumstances. - ML and FL have a history in SS whereas in LMBYK they had not met previously. To be honest I was watching SS and it just really reminded me of LMBYK (although the plot itself is different). So if you haven’t seen it already give it a try.
