Worth the Candle features: - Joon, isekai protagonist with depression and sexual hangups, who previously had an imbalanced relationship with the underage sister of one of his friends - Bethel, magical house and serial killer - Valencia, teenage girl with the power to devour devils and demons for their social or combat skills, who was rescued by Joon and spends a long while wishing for a relationship with him
In canon, Bethel rapes Joon, and then Valencia has to leave the narrative with her to try and rehabilitate her. But... what about if instead of Bethel raping Joon directly, some of their conversations went differently and she trapped them together, compelling them to have sex with each other? This would happen while Joon is avoiding spending time with Valencia as though for fear of what she could convince him of with a devil and time to talk.
Some possibilities: - It isn't Valencia at all, but Bethel taking her form with the body double entad and illusions. Tricky to make this convincing. - Bethel specifically forces them into the time chamber together, which would have the downside that she can't watch or get involved. - Bethel has a forced threesome with them, involving Valencia as a naif to calibrate herself against. - Valencia plays along to avoid Bethel getting more violent or because she doesn't want Joon to think of herself as a victim too? Works better in situations of more ambiguous consent.
Who would be the POV? Probably Valencia, as with a devil in her she can get a clear sense of Joon's state but not of Bethel.
