Just wondering if anyone has finished this series can tell me the ending of the story? I know there is a sequel, but does it have the same characters?

So here's my take on the ending from looking through the volume 6 raw

After some emotional turmoil, the main character guy...forgot his name already gets found out by his kohai that he is in love with their superior. By the end of the volume though they seem to be on good terms. And the main guy and girl [his boss] end up getting married with each other. There's a lot of sex...with love i guess. but it's a happy ending for now. I guess the sequel deals with married life? Kids? we shall see.
