From Oshi no ko ch. 126, Ichigo, the guy in the panel below, realized that he was conditioned by Aqua to go to a particular store from the very beginning.
Notice that in the second panel, 時間の問題でも ended with eclipses. It makes me wonder how 時間の問題でも should end grammatically. The only possible ending I can think of is 時間の問題でもある. I don't know if it sounds correct in this context.
