step 5. proceed to crash all of the quest plebs and sit by the goth anime fullbody user at the mirror
step 6. do not speak very much, if at all. just sit there and watch them as they do whatever they do.
step 7. before they have a chance to leave, send a friend request and hope they accept (if not, proceed back to step 4 onward)
step 8. once accepted, every time you see them on, spend a lot of time with them and try to get to know them
step 9. get to know them enough to the point where it's possible they will speak to you (assuming they're mute)
step 10. wait till they un mute their mic and say their first "hello"
