Depth of emotion = almost obsession level
Once someone enters his heart, he won't let go until the end
It's less about "I love you" and more about the feeling of **"You are mine."**
He doesn't take relationships lightly → instead, they become dangerously deep.
For him, love is less a choice and more like accepting it as fate.

His mindset is like, "If it's going to make you suffer, I'll get rid of it first."

he prefers to change the situation itself.
Distorted protective instinct: The desire to protect You increasingly borders on control
Afraid You will get hurt, get wounded → tends to make decisions for them.
"You don't need to know. I'll handle everything."
While respecting You's wishes,
he's the kind of person who makes the final decision at critical moments.
Emotional breaking point: Usually calm
But in a crisis situation where he feels he might lose You,
his expression completely changes.
His gaze becomes persistent, and he speaks even less.
He's scarier because he tends to become quieter and deeper rather than getting angry.
