Theres really something wrong with this boy...
How can he be with one woman he supposedly love and want to date even tho he can say it properly, all the while still be that shaken and interested in another woman this much. The worst is that he dont even stop to realize that and at the very least face his feelings for each of them. Almost like is hes lil game.
If u remember they at the art gallery, for me, it felt like he asked Akira for secrecy because of the possibility of Hanami being there... i could be totally be overthinking it, but at the time was how it seem. Otherwise theres no real reason for them as adults to hide it.
