in mindscape
steven: huh where am i what is this place????
steven starts to look around in some kind of tunnel
steven: this place is really weird maybe i should start walking maybe this tunnel can lead me somewhere.
steven starts walking to where the tunnel leads him after hours of walking he saw a big door painted red
steven: hmm something is hiding behind a door whatever is that I should go inside
steven pushes the door and goes inside and saw a tall red woman who has hands on her face and crying and while talking
steven: why is she crying I should go and see her what's wrong
steven starts approaching her while the lady crying after he close enough he starts listening to her
???: *cries more* why pink why did you leave me you promised me that we will stick together so why did you leave me alone!!!
*she starts to shout and yelling while crying*
steven:......*jumps on the left hand of chair* umm hey are you alright
*she stopped crying takes her hand on her face and starts to look around until she saw steven on left-hand chair*
???: *shocked*
*steven starts to look at her*

(that's how she looks like, just imagine crying and doesn't have pearl in her lap)

steven: sorry if I scared you I just saw you crying and I just want to help so what's wrong
???: hello little one its nothing it just after hearing that Pink is gone she left me alone she even promised me that we will stick together but now that she is gone I don't know what to do *starts to cry more*
steven: I know its really sad that my mom is gone
???: *she looks at Steven in confusing* your "mom"?? wait who are you and what are you
steven: oh well my name is steven Quartz universe and to what am I, well let's just say I'm a half-human half gem, and what's your name
???: my name is Red Diamond but what do you mean you are half human half gem
steven: well I might tell you my whole life
*time skipping after steven told red his life*
steven: and that's how pretty much of my life end.
red: *shocked and speechless*
steven: *sighs* I know it's okay if you don't wanna be my friend I will just-
*suddenly red grabs steven and kiss his forehead*
steven: *shocked and start blushing* why did you do that
red: *smiles* I don't hate you steven and also after hearing pink what she did I can understand that besides how can I hate a cutie pie like you

steven: seems I finally made you happy
red: *smiles* yeah thanks for making my day
steven: anytime btw are you diamond by chance since you actually tall and big
red: why yes I am.
steven: *shocked and has star his eyes* no way I didn't know you are diamond, I never heard there was another diamond
red: *giggles* that because I live in shadows so that no one knows who I am
steven: amazing how did you meet my mom
red: well it all started when I was at the old ruins where I live I was curious what the outside was like, when I went outside I saw how beauty the earth is and stuff after exploring things i met pink she was really kind after meeting each other we start talking and having fun promised that we will stick together since that day I heard there will be war in earth i was really worried about pink after the war ended I went out to find pink but I couldn't find her until I found a broken gem then I realized that pink is gone I was broken and I couldn't believe that my only friend pink is gone but after hearing your story that pink faked her death and become Rose quartz I start to hate her even more she lied to me, i can't believe i considered her as friend its good thing she is gone now.
steven: yeah everyone starts to hate her except a pearl.
red: well she is just nothing but an idiot who has no brain
steven: yeah, I think you right
red: anyway how did you get in here??
steven: well I was sleeping out of no way I opened my eyes I found myself in a tunnel and that's how I got in here
red: really that explains why you here
