you're in the apartment and lying on the sofa watching tv,It's almost 10pm but you still haven't seen your two brothers back

After a while you hear the door open. It's Ran and Rindou who have returned from their work

"We're home,..."Rindou said as he take off his shoes

"Did you miss us?"Ran enters after Rindou*

they never tell you they work in Bonten and the fact that they always come home late seems familiar to you but they never tell you the reason
