I had an apartment, I didn't notice signs of a pet but definitely a sad family. The guest bathroom had pictures of castles, princesses and knights drawn in crayon on side of sink cabinet next to toilet. There was a scene with a dragon breathing fire at a knight holding a shield towards the fire protecting a young princess from the flames. There was a large wine stain on balcony floor. Multiple sets of knuckle prints on the inside side of the door to the apartment. There was a cabinet hanging I've the kitchen island but there were several sets of screw holes to hold a wine rack which for some reason had to be redone several times, either too much wine and it ripped out or too much anger and it was torn off.
There must of been a couple with a young child having relationship issues...
