yeah probably. i feel the first volume was written the way it was cause thats all there is to jirou and aoi's story. same old alpha x omega whose relationship would have worked out anyway in the end. so there was not much opportunity to showcase a lot of heavy conflict like in the case of ichirou and yuuto. or at least thats what i think...

You know how people always end up liking the second couple in most mangas,
Do you think the author used that to their advantage?
Because they really rushed through the Jirou x Aoi story line and spent more time on Ichirou and Yuuto.
I feel like they were the main couple and Jirou and Aoi were just used to make IchirouxYuuto storyline fuller.
