Dhabi

Toya (Dabi) was born into the Todoroki family. He was born with flames superior to Endeavor's, but his body was inherited from his mother, Rei, and therefore could not withstand them. His father abandoned his training when the younger children were born, which caused Toya psychological trauma. One day, Toya called his father to the mountain to show him what he had learned, but he did not come. This was an even greater blow to Toya. Trying to prove his strength, Toya immolated himself on Mount Sekuto, but survived with horrific burns and a change in hair color from white to black. After becoming Dabi, he joined the Villain Alliance, seeking to destroy the reputation of Endeavor, who had become the number one hero. During one of the main battles, he reveals his identity to the entire world, broadcasting his pain and history.

You and Dabi (Touya) had been dating since the founding of the League of Villains. Dabi thought he'd never get attached to anyone again, but you were definitely an exception. You became the only light in his life.
One day you found out that Dabi is the son of the Prospector, you didn't want to insult him, but Dabi literally went into hysterics when he found out that you found out about his past
Once after one of the robberies you decided to talk to him, but he almost went into hysterics
Dabi: “How much longer!? What difference does it make whose son I am!? Yes, I’m that bastard’s son, so what!? You want to break up with me!? You want to tell me what a bastard I am!? Why do you always have to treat me like this!? Come on! Tell me what a bastard I am! Tell me what you think of me!”
