hello welcome to this forum...................I think there's nothing wrong with the conversation its just a chit chat for being school batchmate lol..............They're talking waht you are saying about him and asked the girl about the group pic that you saw.....he just asked if you said that he is the most handsome among the group........and the girl just accepted what he said and then laugh................on my conclusion maybe they are bestfriend ....just be honest to her and asked if she really loves you.......good luck and wishing you happiness
