Ow, that's a blow, since I write lots of Sakumoto 😯 as you have probably already noticed.
But on the other hand I also write Matsumiya, Junba and Juntoshi. Ohmiya gives me trouble but I can just about manage it if I try.
I've only ever written one Sakuraiba, perhaps I should try it again......they seem to work well together....
Hmm, now that I think about it, I more often write Aiba as seme. It just seems that underneath the fluff he has hidden depths.
