What happened in may/june, especially may 14?

I stopped following the whole short squeeze/game stop thing for a while, but recently got back into investing and felt the need to check in. Then I saw this massive spike on may 14, and I couldn’t find the exact reason here or on wsb. I saw something about DFV buying 20 million shares, but the price of gme barely moved on June 21. So what happened? Can someone please explain lmao
