friend with penalties

A member of the opposite sex, that you know because they make it clear they have been in love with you since you met. You refuse their romantic gestures almost coldheartedly, and struggle to keep them at an arm's length, but safely within the friend zone, because they have some value or benefit for you. Unknowingly, they constantly attempt to make their affections for you more clear sand present them to you in painful obvious ways. Only to be rejected, repeatedly. You have "penalties" like, you refrain from casual hugs, or physical contacts, emotional outbursts or gratitude, for fear they might see it as a positive thing! Some form of an advance on your part, so you have to monitor your standard behavior when around them.
