Help! So I read this manga a long time ago. The boy was once rich but now he isn't so he is just a waste in life he heard that his old Butler was looking for him? So he decided to rob his old mansion (this I'm certain) its actually pretty yandere the master is an idiot stimulated the butler so the butler chained him so he can't leave I think the master even broke but then quickly recovered and got a part time job.
Ahh... I want more of that mansion part that Butler is really possessive he can have the mansion but you can't forcefully own the person that's a crime....but I like stories like that..
Have you read this one yet? http://www.mangago.me/read-manga/ouji_no_hakoniwa/
