Vampire diaries is the best example of having so many lookalikes (Stephan and Elena had just too many lookalikes) then it turned into a mess in the end. Everyone had an affair with everyone and I disliked everyone in the end. Katherine was better off as she was single 😆
Among serials, Rangrasia is one I can think off and even Do Hanso Ka Joda where Shaleen played a double role and met Shivangi in the end when her husband died but luckily she did not fall for him but instead died. The lookalike remained alone.
