This is a vanilla sibling incest romance SOL story which isn't terrible or outstanding.

Ritsu and Uta have a happy, healthy relationship with their friends and parents, which makes their secret all the heavier because if it gets out, it could destroy everything.

Except it never does! When the rival heroine finds out ...
