Yukimura demands the evidence of this discovery. They discuss their research so far and realize that no one piece of evidence can apply to all couples. Thus Yukimura has the revelation the only evidence needed is for one individual to become aware they love someone. As Himuro has concluded she loves him Yukimura desperately writes an equation cataloguing his feelings before declaring he loves Himuro too. Himuro is thrilled, but as a scientist immediately sets new boundaries for their research that says at least once a day they will hug so as to increase the levels of all their love chemicals. Yukimura agrees and is surprised when she immediately hugs and kisses him, not for research, but simply because she wants to. Everyone in the lab celebrates them completing their research. However, they claim their research is merely beginning. While they have proved their love exists they must now research and prove if their love is at the level of romantic partners, or merely friends, and until this new research is complete they are still not actually dating, infuriating Kanade. Kosuke is happy as by the definition of love they have created, he can decide to simply not love Ibarada. Kanade decides to accept that as long as the two know they love each other and are happy spending time together, it will do for now. (Source: Wikipedia)
