This is when you're head over heels for someone but they think you're just a weirdo who knows their name. You're not even close to being friends. You're like a ghost in their life, they see you, but they don't want you.
You text them every day and they reply with 'hi' once a month.
You know their crush's name but they don't know yours.
You try to hang out and they say 'I’m busy, I know you.'
