REPENTE
Repente: suddenly.

Yang Liu looked up at the house ahead of him. Zhou Yongliang said that one of his grandfather's friends borrowed the car last year around the same time as Yuan Boqin's brother's incident, and they decided to interrogate the one who borrowed the car today.
Zhou Yongliang mentioned a name, and they would investigate the owner of the name today. The name's owner was his grandfather's best friend.
Yang Liu himself was not sure whether they would get a clue from the investigation or not, but it wouldn't hurt to try, so he kept his mind positive.
He could see Zhou Yongliang raised his hand to knock on the door, and they patiently waited for the house's owner to open the door for them.
Not long after, someone opened the door from the inside, and an old man greeted them with a smile.
"Ah-Liang! I didn't expect to see you here!" The man exclaimed joyfully upon seeing the familiar boy's sudden appearance.
