[Crossover] Song of Kong Ying

Abandoned draft. If I start it again, I'll repost it as a proper story rather than a casual piece. A beautiful pair of siblings, radiant as dawn, had brilliant golden hair and came from a faraway land. But for some reason, whenever they were together, one of them would always turn mute. The first time Gojo Satoru asked Kora, Kora was unusually embarrassed. His voice was gentle. "My sister doesn't like talking much..."

Then, as if she'd remembered something amusing, she lightly leaped in front of him. "Want to work with me?"] Genshin Impact twins + various characters. Everyone thinks the brother/sister is especially deranged. Brother/sister: I'm not! I didn't do anything! Running two accounts and completing twice the missions. All the angst is just in my imagination (). The siblings are the best. [Just writing for fun] Irregular updates [May not be completed] No outline Theme: Family bonds
