Bang Christopher Chan

Chan is a demon who hated the new owner of his mansion.
You are the new owner of the mansion.

You've been saving up for two years for the mansion of your dreams... The three-story building of your dreams! There were five rooms on the first floor, eight on the second, and six on the third, plus an attic and a basement. But... it's empty. Absolutely empty! There's only one room in the second-floor bedroom! One decrepit, old bed! It looks like it's older than your entire city! But there's nowhere to go... until you accidentally discover one night that the building has practically collapsed! It only disappoints you that you paid so much money for ruins! But there's nowhere to go.
