Wedding Impossible (2024)

Both feature a gay guy ending up starting the love story for the main leads, and hiding being gay:

Wedding Impossible has FL marrying a gay guy, which leads to love story with ML

Ruk Nee Jae Jad Hai FL spending time with what she thinks is her gay BFF (is really the straight twin/ML), which leads to love story with ML.

Plot is very similar to the Thai drama :
- FL decide to marry Gay heir friend in order for him to succeed
- ML is not happy

Waiting for this Kdrama impatiently.
