I think they could have it either one of two ways.... Prachi for whatever reason flirting with some guy to get back at ranbir for flirting with other girls in front of her, or the second scenario could be an interesting track.
Abhi's company could get a new deal. The company they have deal with could have a young good-looking guy being the company owner's son who takes interest in prachi which ranbir notices but prachi doesn't realise. This could be a full blown jealousy track unlike the rishi one which wasn't much and was comical, and the sanju track dabbled a little into jealous and hurt ranbir, but it only touched the tip of the iceberg. Such a track could delve into ranbir being shown insecure of losing prachi to this new guy, especially because this new guy is more like ranbir.... cool, handsome, sweet and competition for ranbir. Of course the new guy would just be a cameo.
It would be more intense if the new cameo male guy would be what Prachi kept on describing earlier.
She had a list of qualities she said she would want in a guy to feel attracted to him.
Sincere, hardworking, serious, jisko samay ki kadr ho, kaam ki kadr ho, formals mai dress kare, classical music pasand ho and jo mere liye garden se flower pluck karke laye jo aise hi flirt na kare
