Why would a male teacher often tease me in front of others but also care about me when no one's here?

Well. He's my teacher and he often asked how do I feel about his class but he never asked others. He smile when he saw me even though he just scolded some students. When he walked pass by, even though I didn't do anything, he would say "good girl " to me. Once I was just holding a book to read, like standing beside the desk at recess, he walked pass by and he said "nice posture, I love the way u stand, so elegant " When he write example sentences on the board, he must include my name and make fun of me. When we're having quiz, he would walk beside me and pick up the books of mine on the floor to read. He had once said to the whole class that the fun fact about me is my legs are so reddish. This makes me feel he likes me and I like him becuz he cares about me. Is this real love? Does he like me or just nothing?

But then I am just 15 and he's 30. Is he way too old? I mean I like young guys but I don't know why I have got some feelings on him...
