I thought I would be okay with this type of ending, but it turns out I'm not. Here is my summary of the never to be released volume three that was leaked to me and no one else:
Ise and Shima decide that because rent is so expensive in Osaka they will be fine sharing a bedroom to save money. They have lots of adorable mini-adventures exploring Osaka together, but the biggest adventure of them all is the one in the bedroom.
Each night they go a little farther. Holding hands, getting really close, playing with each other's hair, spooning, playing footsie, hands explore each other's hips and legs as they spoon, nuzzling their heads into the back of one another's necks. There's lots of doki-doki as we get glimpses of what they are thinking.
Eventually Shima is tired of waiting for Ise to make a move, and when they are spooning she starts kissing her neck. She hugs her tightly and kisses her ear and Ise lets out a little moan.
Ise turns around, "You know if you do that, you're gonna give me the wrong idea."
Shima with a pouty mouth, "Well I wish you would get the idea, already." She puts her arms around Ise's neck and gives her a big kiss on the lips. Ise's face goes bright red, and Shima takes the opportunity to move on top of her. The scene fades out as they start making out. (Turns out Shima is the top.)
Two years later, they are being promoted and transferred again. This time they are excited. As they discuss the transfer with their boss they are holding hands under the table and both have rings on.
The End.
