I wouldn't know these were Mikoto and Kuroko if I wasn't told

Hmm, ... from Page 3, Mikoto and Kuroko are in their 20's, one of them is a futa (if not both), and a ring is offered, implying a pledge to get married.

Can Live With That.

EDIT: the "Futa" factor is not 'au natural'; rather, Mikoto drinks some concoction, and seconds later, "Say Hello To My Little Friend, Kuroko-chan." Conclusion: "Ah, What A Fine Day For Science." (those who recognize the reference will understand).
