Should I write a story?

So, quarantine has really gotten to me, so yeah, I was wondering if I should make a story for my ocs, like explaining their backstorys, or how they met, ect. So yeah. I'm still not sure if I should do it or not though, so I'm going to ask you guys! All my characters, so far are, RoseWater Opal, Golden Lapis, Celestial Aura Quartz, Peacock Ore, Ice Lapis, Cinnabar, Sakura Diamond, Sakura Spinel, Sakura Pearl, RoseWater Lapis, Pink Kunzite, and Bi Sapphire
