Siming (one of the male protagonists)
Identity: The last prince of the previous dynasty, he was chosen by "Heaven" to be the shackle bearer in the world, and he was the "Living King of Hell" who lived for three hundred years. His face is young, but there is an old blood streak in the corner of his eye, which is said to have been splashed when he killed his father and the king.
Personality: On the surface, he is cold and taciturn, but in reality, he suppresses a burning paranoia. He would not only guard "Tai Sui" tightly, but also brush away the fallen flowers from her hair in the dark - that was the last remaining tenderness in his erased memory.
The core abuse point: Every time he uses the "power of holding the shackle", he will forget a past event related to "Tai Sui". Over the past hundred years, he has forgotten who she is and only relies on instinct to guard her, but he doesn't know that every time he activates his power, he is killing their remaining bond with his own hands.
This is how it should be (male protagonist 2)
Identity: The first human obsession before the birth of "Tiandao", "Tai Sui" imprisoned in the female body. Intangible and formless, it can see through people's obsessions. When necessary, the heroine's body can be borrowed to manifest briefly, and in extreme cases, a semi-entity can be condensed.
Personality: Lazy and joking, always joking, but in fact he is a lonely soul who has lived for thousands of years. In the three hundred years since he merged with the heroine, he has already become obsessed with "protecting her". The more critical the situation, the more he loves to laugh, until the corners of his eyes turn red.
The core abuse point: He can't touch anyone - touching will swallow the other person's obsession. For three hundred years, he could only watch the heroine cry, laugh, and get hurt, but he couldn't even help her wipe away her tears. His biggest wish is to truly "hug" her one day.
