Headcanon where whenever both Tam and Linh got in trouble, their parents would split them up, so one would go sleep with them (usually Linh, cuz she was more cooperative) and the other would stay in the room alone. When Linh got too big to sleep with them, one of the twins would have to sleep in the hallway, and the other would be locked in their room.
Sorry this one wasn't written with my usual story-ish way, but it's twenty before seven am here and I am tired 😭
