𝓢𝓽𝓮𝓿𝓮𝓷 just saves the universe and the diamonds insist for Steven to have a pearl. He declines multiple times, but it was too late.. 𝓨/𝓝 was an unexpected earthling forced to be turned into a pearl, mostly for Steven. The diamonds transform her body into a pearl, and after pain and suffering, she's assigned to be Steven's pearl. ( I'm sorry if humans can't become a gem, I just wanted it to be like that LMAO)
