Haha Sure, I can sort of explain it to you.
Ok so Homestuck (also known as Microsoft Paint Adventures or MSPA for short) is an animated online story (Not quite a comic because it does not read in that format) that has been going since 2009, about a young boy's adventure after he starts to play a game called Sburb. His name is John Egbert and you start the story off on his 10th birthday. He, though the internet, talks to and makes many friends. The rest can be explained through these sites because if I were to sit down and really get into thoroughly explaining things we would be here for literal days and I would probably bore you to death.
Here are some sites that will probably do a better job at explaining things then I would.
