I honestly think Taec has feelings for Gui Gui. Remember when they played the Yes/No game? But Gui's answer was a bit disappointing for him. He thought Gui doesn't like her so he took his actions with extra care afterwards, He's just afraid to show his affections for her and he knows that this whole WGM thing will end soon and it will be hard for the both them to separate if they were too attached with each other. I've been a fan of Taec for so many years already and I am telling you that his smiles doesn't lie :)
