>>3338302The title and only character tagged is "Nakano Ichika".
The best theory I could come up with is that she disguised herself as Nino to marry Fuutarou, while Nino had already had sex with him before, unlike Ichika whose first time was on the wedding night.
Or maybe he did marry Nino and Ichika just sneaked in that one night, but in that case Nino should be tagged for being in the photo...
