Koko wa Rakuensou 2

The Paradise Heights apartment has changed after half of your uncle's company got liquidated. After the money went, so did some of the tenants. Now Keigo Nakadai (You) works for a toy making company (but still stays at Paradise Heights).

Rumor has it that a competiting company is stealing your brilliant ideas...and the source of the leak is someone with high rank in your company! Fortunately, the new tenants also work at the company as you join forces with them to find out who is conducting industrial espionage behind your back...as well as some entertainment on the side...
