Ok this guy has to love V like he did in the olden days. I know their love will grow further. How about Sin plans to make Sagar jealous of a new man in V's life. Could be whoever but seeing an insecure Sagar is something I've been wanting to see since forever. During the Sameer scenario, it was rather cute seeing him get up to all sorts of antics to get V's attention. I would definately not complain if V ignores him unintentionally for a while.
As neha said before the dude is taking her for granted. Its time he realises her worth!
