CRUSH was obsessed with OC, unhealthily obsessed. they were fairly possessive over OC, despite them not noticing it. as of recent, OC's friends have all of a sudden stopped talking to them one by one, for reasons that they were unsure of. CRUSH had been sending threatening letters to those they found to be 'too close' to OC. eventually, this left them with no one but CRUSH to turn to and slowly but surely, their possessive behaviour becomes more apparent.
