Shining in the Starlight.

Still trying to keep their relationship under wraps, Nico and Will face their first Valentine's Day together. However, their plans to keep the day low-key are put under threat by the appearance of an unexpected guest; one who has misplaced a very significant item and needs their help to recover it, before it is too late.

Keeping their relationship a secret is the last thing on their minds.
