Três Pais e Uma Mãe (2008)

Similar plot. A pregnant woman lose her husband and three guys take care of her.

Similar plot. A pregnant women both lose their husband/boyfriend and three guys fall in love with her wanting to be the father.

I won't say both dramas are similar bcoz this is more on comedy side. This is "an intriguing story" of finding the real dad.

They also had one baby & three men living in 1 place & we get to see how they struggle taking care the baby while make a living too. Both drama are fun & the baby is just as adorable.

It's also with the same actress and about getting pregnant and all the complications involved to raise the child after her husband die.

Three Dads, One Mom - After their friend dies, three guys reluctantly help his wife rise their child. After a while all three start to fall for both the baby and the mother. All in all it is a very funny and sweet drama.

+ Both FL are desperate to get pregnant
+ Harem Reserve
+ The stories revolved about three guy around FL that would became father of the baby.
+ Even tho I'm not really sure how the story on OMB goes, but I found both drama has pretty similiar. Both are comedic and fun to watch

I will add more later

Both dramas have a similar plot line about three men with different personality handling a baby.
