Secretly Love you

After three years of divorce, his ex-wife became a bodyguard. He asked her how close she could be, but the two of them stuck to the bed. She had a deep hatred towards him, but he didn't know what was going on with her. The two of them clearly couldn't fall in love, but they just had to walk together. Besides eternal damnation, they also tortured each other.
Three years ago, he had understood the truth, but three years later... He was still immersed in this feeling. The love that happened by accident, the overlapping misunderstanding of conspiracy, caused the two of them to walk further and further away. When she found out the truth, she discovered that his love was so deep. So early, even she didn't know. But wouldn't all of this be too late?
