Let's better leave

Some time ago…

Sei and little Shin were rushing towards the mansion as soon as he received a message telling him that the old men went to the mansion again without prior notice. He was also told that their parents were also with them so Sei quickly sent Zaki a message to at least inform him. 

When they reached the house, the old men immediately complained at him for making them wait for too long outside before relentlessly asking about the whereabouts of Zaki.   

"Son, where's your brother?" Mrs. Chen asked as she took little Shin in Sei's arms. 

"I believe he's still asleep upstairs." He answered and everyone looked at him in surprise. 

"What?! That little punk is here?"

"Wait, Sei. Don't tell me you locked up your brother here for an entire night till now?!"

When Sei remained silent, everyone already understood that he really did, causing them to sigh heavily.
