I really get the feeling that we will see a threesome in the 3rd period and that Azuma and Shiratori will awaken the sleeping beast that is Takemoto. Hang in there Takemoto, you can do it!
"Did you really think you could fool me when I have to clean up your mess every day"? That's...A good point.
Also, I always thought the maid was an interesting character since the end of Chapter 1, so I'm definitely happy to see her getting some love in the sequel. Heh, and she was the one that initiated it. After being shown them having sex everyday, she decided she also wanted some and decided to...'coerce' him into having sex with her.
Great ending though! Ah yes, and as a result, he has unlocked the 3P route...What a lucky guy! Also...Any chance of a 3rd Period of the great sexual education?
