1. I came expecting nothing, a mafia concierge born in Korea and coming back to korea
2. No romance but a couple fighting crime
3. Didn't know any of Jeon Yeo Bin dramas, and wasnt a fan of Song Joon Ki because I couldn't bear watching DOS
4. comedy, thriller, drama, mafia genres
5. like 2% of romance

Let me tell you
1. The plot is not all that, is more far and beyond
2. Never been a fance of thriller, crimes etc. but romance but I enjoyed every single interaction of the main leads like I was watching a romance drama.
3. After Vincenzo one year later, I still can't let go of my love for this drama and the main leads I became instantly a fan of both Jeonki together or in separate projects (but deep inside i want them to reunite in another project)
4. I never knew they could blend all these genres and make a beautiful drama that will be in my memory forever, they blended all this elements that one minute I was laughing my a..off then i was scared then I was mad Ohh my Gosh all the feelings, I would wake up every Saturday and Monday to watch 1.20 hrs of episode which took me like 3 hours because of the rewatch value, never happened before ever.
5. Yes romance is like very soft, slow born and minimal but every single scene is about them being together sparkling enormous chemistry.

So yes, even me been biased because I love everything about this drama, please don't get fooled by episode 1, I did get hooked since episode one but Ive hear many of my fellow Vincenzo fans took until episode to really kick off on them so yeah give it a try will not dissapoint.

OST-wise they don't have many songs but the few they have are in my mind 24/7 my ringtone is Ill always be by your side and I change it eventually to Adrenaline.

Rewatchable value 100%

BTW, I never give reviews but I thought I needed to for future viewers not that the drama doesn't have a high rating but because is well deserved direction and writing is phenomenal plus the acting of every support cast. Give it a try you won't get dissapointed.
