This is a south park creek (craig x tweek) story.
Tweek and Craig were pretending to be a couple for a long time. But all of that was about to change when they went to a sleepover at Kyle's house.
Craig and Tweek are a match made in heaven, or so everybody thought. Tweek soon sees Craig cheating on him with Kenny. Not being able to take the pain, he attempted suicide, which failed. Craig doesn't know why Tweek broke up with him. Craig is soon exiled by his peers and Tweeks begins a letter. A letter explaining their relationship and everything that ever happened between the two of them.
