"Do you understand?"

...

The child's expression was a bit dull.

He seemed to understand...

I don't seem to understand...

...

“…Where is Dad’s phone number?”

The child finally managed to sort out what his grandmother told him.

A flash of inspiration flashed in his mind.

Since Dad doesn't use this number, what number does he use?

The child looked at grandma expectantly.

His eyes lit up again.

...

"Dad has no phone number."

...

pity.

Grandma Yu's words were like a basin of cold water that extinguished the light in the child's eyes.

...

"Why!?"

The child doesn't understand.

"Why don't your dad have a phone number?"

...

"Because he doesn't need it."

Grandma Yu is very calm.
