He saw a rude and obnoxious girl at their first meet, but gradually when he realised she is also a person who's intelligent, loves her Aaba unconditionally, he started to warm up with her. He fell for her when he saw her being the child she's, but a mature girl at the same time loving his Aai, caring for his Bua, his brother, standing up to the right. For Pakhi, he saw her outer beauty, how she's beautiful and may fit into his family.
His feelings for Pakhi wasn't strong, that's why whatever he felt at that moment vanished away with time. We also fall for fictional characters but over time, we may like them but the strength of the likeness get diminished over time, because the love isn't true there. But we love our parents, our close family members, our spouses but it increases over time, because the love is true! For Virat, what he feels for Sai is true love. And it won't diminish or change rather will increase more and become stronger. Yes, in real life there are cases where people grow out of love, but there are cases also where people love the same person their whole life.
About Virat being manipulated by his family, yes he was being manipulated but not now! He saw his family's behaviour towards Sai and his relationship very clearly. He saw how his family behaves towards him. He won't let ever himself to be manipulated atleast from her.
Even as you said, he won't ever blame Sai for failing in the mission, because Virat's one of the best qualities is that he never does blaming shifting. He owns up his mistake.
