Double Bubble

A guy runs a covert operation to keep his own family member safe after she blows up as a model under a fake identity, and she never finds out he's the one doing it. The setup plays out as a tense visual novel rather than a comedy, with the danger coming from men who want a piece of her and the constant risk that her secret gets blown wide open.

The story is built on that gap between what she knows and what he's actually doing behind her back, which drags the plot into ugly territory: manipulation, coercion, and men closing in on her whether he intervenes or not.

Play centers on managing that protection game from the shadows, moving through a school-adjacent sandbox and choosing when to step in and when to let things happen. Corruption and exposure risk seem to be the two dials the game keeps turning, and the horror tag suggests at least some of what he's protecting her from isn't subtle about it.
