Hello, OP

It's really difficult to stay away from something that is addictive, and I'm not just talking about drugs or addictive substances. There is definitely some type of lure that this guy has, to make you crave his attention. In our brain, that's just being registered as a Dopamine effect, similar to falling in love for the first time.

For some odd reason, this guy triggers that effect in your brain.

Sounds really weird, but yeah, you're addicted to this person's attention.
