new school syndrome

when someone joins a school, and instead of adapting to the new environment and making new friends, they latch onto one person and only talk to/ follow them around. they may briefly interact with this person’s other friends, but will not try to become real friends with them.
during break, at parties, or meet ups they will only stay next to their target.
this usually takes the form of a romantic/sexual relationship that develops at an unusually fast rate at the beginning of the school year, but can also be platonic.
an infected person will become dependent on their host, as they are their only form of social and physical connection in the school and they cannot afford to lose it.
there is currently no cure for this syndrome, and the infected must try to overcome the anxiety of a new school and make other friends, as if the relationship falls apart they will be left completely isolated and alone in the school.
