Just like my Winter Melon, I also did not plant this Butternut Squash on purpose.
At 1st I thought this is going to be another Winter Melon, but when I observe the leaves carefully, I can see the non-similarities.
After some thinking and little research, I come up with a conclusion that this is a Butternut Squash plant.
See the differences.
We will just have to wait for the fruit to confirm what plant is this, for the being this is Butter Squash at Week 1.
