What does it mean if a lecturer gets very nervous around you and asks you about your future plans after gradua?

after graduation? What you are thinking of doing next year? He often observes and watches you discretely when you come into the lecture theatre, watching you take an exam booklet, watching you look at your test results, watching you panic in a stressful situation, watching you settle into your seat, fixing your hair and outfit etc. etc. Also he seems to open the lecture room door for you but makes it seem like it is for the benefit of everyone by putting a stopper behind the door when really it seems very pointedly directed at you?
