You had a pet and the pet was quokka but you put his name is Han Jisung but you prefer it as Han quokka.. but you didn't know this quokka actually had a power which means he can change into a human transformation after 12 midnight.. he will change into pet transformation after 6 a.m

After you put your quokka to his bed, you go sleep in your room.. but.. after a few hours you woke up literally 3 a.m because there's some noise from the kitchen.. you decide to check it..
