Fake relationships are one of my favorite tropes. I expanded the theme a bit and cast a rather large net (so quite a few won’t have the because this is my first life feel). Hopefully you find something enjoyable or time killing. All match the theme but not all are what I would consider “good.”
1 percent of something and the older version 1% of anything - contract dating
100 days my prince - not an actual “contract” but definitely a marriage of convenience for the FL
Bride of the century - technically not a contract but an arranged marriage and also the FL is pretending to be the actual bride.
Crash landing on you - ML pretends FL is his fiancée at one point
Goong - arranged marriage
Hapimari happy marriage - jdrama. Marriage of convenience
Lie to Me - fake relationship
Marriage contract - self explanatory. I loved it, but it’s super emotional as a heads up. Only drama to have made me cry of 150+
Mask - See bride of the century’s description.
My husband oh jak doo - contract relationship
Perfect and casual - cdrama. Contract marriage. Super cute and fluffy IMO but disclaimer he’s at one point (before their marriage) her professor. Normally I’d avoid the plot as a college student and child of a college professor since it’s kinda creepy, but I thought the show mostly handled it well.
Please love me - cdrama contract marriage
Prime minister and I - contract marriage
So I married an anti-fan - c-movie. Stars exo’s chan yeol arranged relationship. I’m still waiting for the kdrama version to come out
W - not really a contract relationship but the ML at one point fakes the FL being his fiancée
Marriage not dating - contract dating
Pretty man - cdrama contract marriage
Well Intended love S1&2 - cdrama. Same story different universes, so it shouldn’t matter much which one you watch. Marriage of convenience
The eternal love - cdrama arranged marriage
Ending again - contract marriage
Shanai marriage honey - jdrama marriage of convenience
Goblin - arranged dating
Honorable mention: The master’s sun. MDL says it’s a contract relationship, but personally I don’t think it fits. I do love the show, so I’m listing it anyway.
