Help me find this Bollywood rom-com shot in the UK with a debutant actor!

I need help finding a Bollywood romantic comedy film released before 2020. It was shot in the UK (or a similar location), starred an unknown actor or a debutant, and had a funny slap scene that stood out. I can’t remember much of the plot, but this detail has stuck with me. Does anyone know which movie this could be? Any help is appreciated!
