While an enjoyable watch and the story is good, the title and summary provided in the site is misleading as this series focus more on the back story and the revenge plot of the antagonist. The so-called "shop" and even the niece were mere plot devices.

The back and forth between the past and the present provided a great way to stitch the narrative together and helped the viewer find out why assassins were after the niece. But then again contrary to what is on the title and on the summaries, the assassination attempt has nothing to do with the shop or the identity of the niece but has to do with what happened in the past.

It feels like the element related to a Company takeover of the shop was shoved in just so the title would make sense. At its core this is a revenge drama about a villain throwing a tantrum because he was chastised in the past for his criminal deeds.
