Marriage of convenience does happen and this drama lightly delivered the message. What a convenient marriage could turn out to be: lifetime friendship. ML and FL didn't enter an arranged marriage out of wickedness or for the sake of some inheritance. The ML really won over FL head and heart first before the marriage begin. The sick grandpa and demanding sister have only escalated the process.

Yun Shu wasn't as smart as Mu Wan Qing (Fall in Love) but not as dangerously dumb as Xiao Wan Zi (Truth or Dare), and Zhang Sinian wasn't as perfect as Xiao Nai (Love 020). Shinian is wealthy, but the apartment was aligned with the story. When you are single and academic chances are your house will be super smart-tech (if you are hefty) or super fit. If you don't have anyone looking over your house, then the house you choose must be practical to be taken care of. That is what this drama offered. Unlike some drama where the wealthy ML must have a penthouse-looking house.

The main love story plot that I like about this drama was FL and ML realizing their fall in love because they enjoy each other companionship. Not because ML was a superman or FL has perfect traits.
This kind of plot is easily overlooked because, in the sea of Asian dramas where FL is often portrayed super dumb or ML portrayed superman, this light story plot won't make you exciting over the roof, but you will nod for the realistic situation.

Every time the leads try to clear up their misunderstanding, I eagerly nodded my head. Cause, well, you solving misunderstood problem with communication! You talk! As simple as that.

The chemistry between FL and ML was okay. It's not sparkling fireworks like Zhang Zhehan - Jun Jing Yi or Yang Yang - Dilraba Dilmurat. But I think, the supporting roles have lacked of chemistry. Even the friendships didn't look sincere, the supporting love story didn't deliver any excitement, and the intimate part didn't have the makes-you-giggle effect. The second ML didn't give his life and everything for FL unlike most asian dramas, but sadly he easily gave up his what-so-called love for FL.

The rewatch value is 10 though because this is the most realistic, light, logical drama I watched.
I hate when a ML seems to understand the insightful thinking of their partners which are NEVER HAPPENS in real life. Yow, gurl out there, let me tell you that if the man that truly understands your thought exists, then this world is close to its end. No kidding. In Perfect & Casual, the ML had to project FL thought based on his statistical thinking. In real life, this is true, because most men will base their actions on what they thought was right, not what they felt right. Besides, this drama pictured that falling in love doesn't need someone with perfect traits, you just roll with it.

Bottom line, this is a must-watch drama. Go get your hot cocoa and chips for this drama was sweet!

Updated: for the music score. Gotta admit, later on somehow the OST Mr. Perfect & Miss Almost constantly rewinding in my head :D. So, I guess their theme song is obviously catchy .
