Hee-Do and Yi-Jin's Relationship Timeline Will Make You Root For Them Even Harder

So, the big question is, do Yi-Jin and Hee-Do last as a couple? At the end of episode fourteen, Hee-Do's daughter in the present day, Min-Chae, watches an interview between the pair on YouTube, and Yi-Jin and Hee-Do appear to talk as if they haven't seen each other in years. During their chat, Yi-Jin also congratulates Hee-Do on her recent wedding. Does this mean they break up because their jobs pushed them apart? Not necessarily. Some fans are convinced the two get married and hide their relationship from the public.

To see how Yi-Jin and Hee-Do's love story ends, make sure to watch the last two episodes of "Twenty-Five Twenty-One" on Saturday, April 2, and Sunday, April 3.
