I agree with a lot of ur guyses reasons...but jus came up with another one
What if...by pretending to be her boyfriend he wants to show her what a nice/sweet guy he is and what a sweetheart he will be in a relationshippp.Yeah yeah yeah? LOLBut yeahh the overwhelming reason is that he wants to protect her. And like the way he winked, I found it a very reassuring wink. It was like "I'm there hun. Don't you worry!" Don't u just love how used "hun" ehehehhe. And then secondly, he needs excuses to be with his "Miss Arohi" LOL.In the end...whatever it is....I CAN'T WAIT!😃
