Another 'drama' that will most likely be disregarded then back to the fluff by next chapter as always. This is what I like about this series. Hano really know how to tease her readers.
And, let me guess, based from the chapter preview thumbnail from the raw, Ami will come and rescue them somehow. Despite declaring herself their rival, she actually have been help keeping the siblings' secret for a while now, and will probably continue to do so.
