The professional heroes might get involved. All Might, if he's still around in the fanfiction, could use his experience and power to find Deku. He could lead a team of heroes, like Endeavor and Hawks, to plan a rescue mission. They would analyze Toga's patterns and likely places of hiding, and then swoop in to save Deku.
His friends could come to the rescue. Bakugo, for instance, might use his explosive power to break into Toga's hideout. He's always been competitive with Deku, but he also cares about him deeply.
Deku himself could find a way to escape. He's smart and resourceful. He might figure out a weakness in Toga's security or use his quirk in an unexpected way. Maybe he could create a distraction with his One For All power and then make a run for it while Toga is distracted.
Well, one possibility is that Toga kidnaps Deku to get closer to the heroes. Maybe she thinks she can use Deku as a bargaining chip to make the heroes do something for her. For example, she might demand the release of some of her villain friends from prison.
Their relationship could start with mutual self - interest. They both recognize the power and chaos the other can bring. For example, Toga's ability to transform could help Villain Deku infiltrate places, and he can offer her protection in return.
One interesting Deku and Toga fanfiction could be about them forming an unexpected alliance. Maybe in a world where the hero - villain divide is not so clear - cut, they team up to face a greater threat that endangers both heroes and villains alike.
Deku might be completely shocked at first. Since Bakugou has always been so aggressive towards him, he would never expect such a confession. He might just stand there, mouth agape, not knowing what to say.
His friends could use their various quirks to track him. For example, if there are characters with enhanced sense of smell or the ability to detect energy, they could start the search. Then, they would plan a strategic attack on the kidnappers' hideout.

Midoriya's friends like Uraraka and Iida would be extremely worried. They would immediately start looking for him. Uraraka might use her quirk to search in the air, while Iida would lead the ground search with his speed. Bakugo, on the other hand, would be furious. He would probably go on a solo mission to find Deku and take on Todoroki without hesitation.
Maybe Villain Deku and Toga team up to take down a common enemy that has wronged them both in the past. As they work together, a strange and dark relationship forms between them. Toga starts to develop deeper feelings for Deku, but he's only focused on revenge at first. However, over time, his view of her might change.
