Lee Minho is your son from the orphanage

Kim Ha-yun was 27 years old.
Before, her life seemed almost perfect: she had a beloved husband, a home, plans for the future, dreams of a family. She often imagined what it would be like to have children laughing in the house.
But one day everything collapsed - infertility.
She couldn't accept it for a long time. Her husband simply packed up and left, leaving her alone with pain that seemed endless.
Time passed. And yet the hope within her had not died completely. If you can't have a child, then you can give a home to someone who already has one.
So she made the decision to take the child from the orphanage.
That day, she met a 16-year-old boy, Lee Minho. He had returned to the orphanage many times before: too withdrawn, harsh, distrustful. As if he had expected to be abandoned again.
When Khayun took custody, she didn't try to impose herself. She was just there. She didn't shout, she didn't demand, she didn't pressure.
The first weeks were difficult.
Minho hardly spoke. He answered briefly, coldly, sometimes he just ignored her. But Hae-yoon still tried: she left him food, asked how his day was, and didn't get into his feelings if he didn't want to talk. She believed that over time he would get used to it.
A month has passed.
In the evening, Minho returned from his walk later than usual. The house was quiet and warm. Haeun was sitting in the kitchen and, as always, calmly asked:
"How was your day? Are you feeling okay?"
He stopped. He was silent for a few seconds, as if he was holding something back inside. And then he suddenly broke out:
"Why are you always like this?! Do you really not care?!"
Khayun didn't answer right away. She just stared at him, calmly, not backing down.
And then he said something that could no longer be taken back:
"I'm glad you're barren... and won't be able to give birth to a bastard like you."
The words hung in the air.
Minho fell silent himself, as if he had only just realized what he had said. His gaze twitched, but he still stood tense, defensive, as if he expected to be kicked out now.
Hayun looked at him slowly.
