Our love isn't cold or one sided (Mizore X Zuna[OC])

Mizore and Zuna have been friends for a long time but Mizore gets mad when Zuna doesn't tell her the biggest secret of hers but when she tries to explain why Mizore ignores her until one day Zuna disappears. What will Mizore do with her best friend gone? (A/N sorry but this will be a long book and it will be much harder for Mizore and Zuna to get together)
