That night the dorm became a complete mess. Nayoung unnie was chasing sejeong around the dorm. The beagles - Somi, Doyeon, Yoojung, Kyulkyung and Yeonjung - were all egging on the fight. Poor chaeyeon omma was busy settling the hyper beagles down. Mina and sohye sat in silence watching the show, enjoying their late night popcorn snacks. And Chungha was so tired that she fell asleep while watching the whole saga, dreaming a surreal scene of puppies chasing each other round in their dorm from dawn till dusk.
