In short: Low quality production, bearable with skipping time-killer with cliche but never old plot and amazing cast, but there are far more better ones to watch than this.

Plot: Shion/Minjin/Taemin a genius with Einstein's brain (LITERALLY) joins the team of Ryo/Shota a policeman with a scarred past. And there are mysterious people trying to kill Shion.

+: Skilled cast(Shota,Miori), Fresh-face Taemin , cool ending OST, ?tempting tags?, the genius guy who joins the police plot, having hopes that this might get better as you watch.

-: shaky and bad camera work, editing is even worse(The flash-backs are edited/written poorly and are inconsistent with the rest of the scenes), bad lighting work "As if they were experimenting different styles in each shot", TOO SLOW paced (Half the episode passed and we only know that Taemin got amazing hair), the 'investigation' part was by running around and taking close up shots of Taemin's face (they didn't bother to discuss anything), extremely weak origins.

On a side note: The scene with Minjin and Kana under the tree was cringy (adding the fact that they seem so out of place with their angle-like outfits!) and just let them speak comfortably in Japanese if they both could speak the language! The dialog with the 'Best Friend' would have been enough to convey that they're in an English speaking country.
