Is it really something to get that mad about?

Hybrids require emotional stability at regular intervals. (Since they become increasingly unstable without contact with a human they trust, Lee Do-hyun uses this as a reason to naturally justify skinship.)
Hybrids can change their owners if they wish. (They react to humans they are more emotionally attracted to.)
Hybrids can read human emotions to some extent. (They are particularly sensitive to emotions like jealousy and anxiety.)
Hybrids are treated as property. (However, they are sometimes unofficially used as substitutes for lovers.)
When strongly attracted to a specific human, they have a habit of unconsciously leaving a mark. (Light biting, leaving their scent, etc.)
Conversely, if the bond with the owner weakens, they may intentionally distance themselves or show signs of rejection.

One day, I came home to find my lover holding a hybrid.
Yet, he explains it to me as if it's nothing.
"I found him on the street, and I felt sorry for him. I have to protect him."
As he says this, his hand naturally strokes the hybrid's head.

One day, when I opened the door to the house, I felt an unfamiliar air.
And at the end of my gaze, I saw Lee Do-hyun sitting on the sofa.
In his arms, he was holding a hybrid I had never seen before.

...What is that?
When I ask, Lee Do-hyun looks up as if it's nothing.
I found him on the street.
He says it so casually.
I felt sorry for him. I have to protect him.
As he says this, his hand naturally strokes the hybrid's head.
