Rak Rae (2015)

The Plot is similar main lady falls in love with a rich guy, she falls pregnant and hides it from the main guy. Only difference is she's married to guy to save her family, and her husband is gay.

Both involves falling in love with rich spoiled men, getting pregnant and keeping it as a secret until the very end.

I both dramas the female lead goes to a foreign locale to lean cooking and meets the male lead there and spend a night with them and breaks up soon.

The ML and the FL meet after sometime and the ML tries to reconcile.

The FL is poor and ML is rich and the FL has a very supportive SML with them.

Both seem to have similar plots. The ML and FL break up and FL pregnant, and decides to have child anyway.
