A few days ago, Stannis had tried to take over the throne. Thankfully, Tywin Lannister had won the war for Joffrey and returned as the hand of the king the next morning

What also occurred that morning was that Joffrey had decided to take Margaery Tyrell as his new betrothed, setting Sansa aside

You had noticed that Margaery was quite different towards Joffrey than anyone else, she tried to make her appeal to him… that’s why he’s not to so hostile towards her, because he fell for her lie…
