Just plain lost in this whole arbitrary versioning. Confused as to what the plot is (jokes aside) at this point.

The basic plot is:-
MC's some perverted little S**T who wants to pimp out his "landlady" and make himself rich.
But the MC have a few issues with his little scheme.
a) The MC has a rival whom not only wants to pimp out his "landlady" but also his "Flatmate" and Himself !
b) The MC has an Aunt that is helping his rival to gain control of the "Landlady", but she also has her own little plan,
She wants the MC and his "Flatmate" as her own personal playthings !
c) The MC is not as smart as he think he is,
In order to distract his rival/aunt, he offers up his "Flatmate" (But she is already willingly working for the rival)
d) The MC's dick has a higher IQ than his brain!
(He is easily distracted, a fact know by and used by his rival)
