What do you think?

Is it:

Tenjin and Sanae-chan?
Midori and Yuusuke-kun?
Futaba-chan and Yuusuke-kun?
Bacchi-gu and lino Chigusa?
Bacchi-gu and Reika?
Ichiban-Boshi and Futaba-chan?
Or Yuusuke-kun and Sanae-chan?

I think Futaba-chan and Yuusuke-kun. But in the end the couple is Yuusuke-kun and Midori-chan...
