This is different than most ABO stories, which is rather refreshing. Shunya and Ryouta are best friends attending an all alpha school, but Shunya especially has big plans for trying to help omegas following in his father's footsteps with research and advancing suppressants. This research takes on an even more personal touch when he has to ask if participating in a clinical study may have influenced how he suddenly becomes an omega. Fortunately, only Ryouta is around at first when it happens, and his friend is loyal if nothing else, though Ryouta has also been attracted to Shunya from the day they first met. Their relationship is more than a little chaotic and murky after this change, though it's clear that both of them still greatly value their relationship with the other. Even though they have each other, it seems navigating this new reality won't be as easy as either of them may have hoped in the beginning.
