I am not exaggerating, this drama is phenomenal, I highly recommend it if this is your first time watching cdramas!

The storyline begins in the present time which is actually a good attention grabber. It will make you wonder what happened, why and how did it come to this point. The drama will then take us back to the past where it all began, freshmen year of college. The concept of this drama is computer programming, and you really see them mostly focused on typing codes, and make programs, etc. Albeit, I'm not sure if the coding itself is real but I have not seen this kind of drama elsewhere which is quite unique.

What really makes this drama come to life and why its so popular is the acting, the chemistry, character development and the storyline.

Zhu Yun (Zhang Jing Yi) : Zhu Yun as a character is a book smart, follow the leader kind of gal in the beginning but eventually she will find her voice. She can get a little bossy, and sometimes I think she lets her emotions make the decision instead of thinking from a practical point of view. She's very passionate when she wants to prove she can do something, as well as very caring and understanding of her friends espeically towards Li Xun. Zhang Jing Yi played her part very well, nothing to outstanding and her acting is quite natural - like she truly is the character itself who's in love and willing to do anything for the love of her life. I have only seen one drama of hers so its difficult to judge if she improved or not - seems like the same to me.

Li Xun (Chen Fei Yu) : Li Xun is your typical rude, selfish, arrogant male lead who believes everyone sucks at computer programming compare to him. However, he's very misunderstood, he's more of a practical guy - he has more experience in the field thus he knows what is sellable or not. Many viewers, espeically if they don't understand mandarin, would think that he's always rude but most of his replies esp to Zhu Yun are quite funny or sarcastic - its unfortunate its not translated well into english. :( Li Xun may be your nerdy, introverted quiet kind of guy but towards Zhu Yun - he cares in a subtle way, and tend to keep a lot of things to himself which is a double edge sword. His character develops pretty nicely, he's not always like he was in the first few episodes. He learned to be apologetic and show remorse for what he has done. However, he still keep things to himself, and sometimes he believes its better to work alone than to bring people in to help him. Yeah, he definitely needs therapy to deal with the losses and feelings. Chen Fei Yu did an amazing job as Li Xun because his eyes does a lot of the acting when he doesn't talk, and it really sucks you in. I also only seen one other drama of his, but despite of that, there's a huge improvement in his acting!

There is a couple time skips and unfortunately we do not see much of the beginning relationship between the leads, but regardless, their relationship was very cute, fluffy, and natural - its like they're a real couple honestly. Amazing acting from both of them!
There's many other great actors in this drama but I have to highlight is Gao Jian Hong played by Zhao Zhi Wei. Without spoiling too much, his character is very competitive, and insecure in his computer programming skills. I did not like his character from the get-go, he seemed fake - a two-faced character. Other than that, you would have to watch and see why his acting was amazing.

Ren Di played by Jenny Zheng: From the beginning of the drama, the way Jenny acted as Ren Di seem so incredibly natural as if she played herself. I just wanted to point that out, the outfits, and her personality fits the actress so well - its very natural and I hope she gets a main role. She honestly compliments well with Chen Fei Yu - the tall couple. hahaa Okay but in reailty, the characters have no romantic interest to one another.

In terms of love triangle, there is one, however it will not make you pull your hairs out so its not a big deal.
Music is amazing, the settings are amazing esp when the main leads got together - the background, the cinematography was beautiful.

Definitely highly recommend this drama if you enjoy watching dramas in a college setting, slow burn but realistic and natural romance, computer programming, games, the dreaded angst, friendship, and betrayals.
