Search Results: becoming more than friends

We are both relatively shy, so a friend really does the exchange of dialogue for us at times. Basically my friend at one point gave him a tip I had given her. She told him and he loved the idea and he suggested his own idea for me to further improve it. We usually don't talk but one day the ice kinda broke a little. He kept mentioning my name, saying I was more innocent than my friend and Ig sweeter. At the end he said bye to me, he usually doesn't do anything. He turns back frequently or gets in these awkward positions to see how I look. He mimics my movement from time to time. When I leave he turns slightly. If I see him looking he'll just turn away. Today my friend was saying he kept asking about something , like a class and what grade I had gotten. He was particularly impressed by my achievements in this. He took the same class and wanted to know if I had gotten a high score. She said he talked about the other things I could do in the future with my acheivement. What do you think? Is he beginning to like me or?
ps- he's my besties brother
she talks about us becoming a legit couple all the time is it promising?
