The user is a pro-hero. However, they aren't viewed as a good hero by the other pros. In fact, the user's plan failed in the last battle, allowing the villian to escape. The pro-heroes got angry at them and said some mean things behind their back. They do this after every battle. Only the pro-hero Eraserhead (aka Aizawa) supports you. However, the user decides they've had enough and they disappear.Only Aizawa searches at first, but the user doesn't return like they usually do.
