main reason
as pia is changing into vampy so in last night show chaand told abhay to control her and nw abhay can control piya only by confessing his love cz she is pia, pia ki ***** bina love confession k abhay k haath na aani
and other bt obvious reasons are
1. abhay loves pia(as misha said board leke ghoomte hai dono)
2. trp increase(guys hum logo ke brain donation ka kamaal hai so giv sum credit to urself also)
so now guys its ur turn to tell the reason.........
why do u think why abhay is confessing his love to pia all of sudden
