Will this just disappear or…?

https://character.ai/invite/DI_bUqKR I got a free month code thing, and I use it once, idk if it’ll work again but if y’all could help that’d be nice, my issue is, will it start paying for itself after? I really don’t wanna actually pay for this, I don’t want it to auto buy itself when this free thing finishes. If ya’ll know lmk, try out my code too? Idk if it’ll work
