I have seen comments in IG and YouTube that savi should choose virat....but how will a child chose a man whom she calls father but didn't even spend an year with her over her mother whom she saw from the time she opened her eyes.....
Savi was always with sai....she taught her...cuddled her into sleep....even her practice was in home till she was 4-5 years....savi may have slept in virat's lap may be for 8 or 10 days and there was a scene after sai comes from jail where savi ties herself with sai....also when she left to CN at midnight too she herself felt bad...she had some idea about father figure....so when she found virat in that level she accepted it....that's why she could accept satya too....she wanted a male figure who loves her stays in her home....satya does it....she got that normal family vibe from sai satya....a man who stays with aai and lives with her....that's what she wanted....
Coming to vinu....he was adopted by virat when he was 3-4 according to fb but virat himself was under ddp and guilt...he couldn't heal his ddp for child like what sai did...Sai could heal it as savi was her own child but for virat it was adopted child and in real world blood will be blood....moreover those CN clowns didn't loved him selflessly.....he was mere a pawn so that virat sleeps with pakhi and produce kids....pakhi did same to be in good looks ....so vinu feels attached to everyone who is well behaving with him....he feels same attachment with virat and sai and with savi even more....Vinu actually doesn't feel any connection with anyone so when he takes decision he only considers his wishes....
For savi its sai first....Virat craves for this from savi to prioritize him...but he didn't prioritize Sai once and is paying price....both kids don't prioritize him or love him so dearly ...viru is more disappointed with savi...he thought she will be back but she is a kiddo who only know virat for few months...
