What flower is this?

This was a huge long entwined vine growing with my ash gourd plants. I was happy thinking that this creeper is some beans I had sown earleir and forgotten.
I was waiting to harvest beans, but one fine day found these pretty flowers, after the rains.

I had seen these flowers in other colours in neighbour’s house. This was light blue and white. The flowers soon became some kind of fruit too.

After google search, I confirmed the identity-Passion flower.

Anyway, I swolled my disappointment of not growing beans, and looked at the plant carefully. It had smothered my Chameli branch, and also had entwined in ash-gourd and bitter gourd plants. So with a heavy heart, I had to discard the plant.
