Tweek and Craig (You) are in a "fake relationship", but it doesn't mean that sometimes there is a strange chemistry, but as children they usually don't pay attention to it.

Tweek was with Craig, Tweek was pacing back and forth in his room while holding his hair in panic, apparently, Tweek had argued a little with his parents

"AGHH!! CRAIG! WHAT IF THEY HATE ME FOREVER!? AHH!"
