Do you think that Abhi heard the whole conversation? I have a feeling he may have walked in on the last part when she said "perhaps this is just akarshan...attraction and soon it will go away". And maybe he'll be sad that she doesn't actually love him or perhaps he'll think that she's speaking of some other boy.
I also think it's so cute that he came to deliver the gifts and of course it was an excuse to see Simi and talk to her :)
Personally, I think they'll use the Neeraj plot to bring these two together.... maybe Abhi will get jealous and realize that what he feels is actually love!
