I'd just like to state beforehand, that I'm a fan of TFBOYS, so that's why I watched this!!

Story:
Story is set in the year 2050, where AIs with red eyes have been developed and work in certain areas of life. A new and super-improved brand of AI with blue eyes has also been developed without permission and has escaped the laboratory, and has supposedly harmed humans, so everyone is trying to go after it. The three boys find out that the new brand of AI is in their high school, so most of the story is centered on them trying to figure out who is the blue-eyed AI.

As someone who greatly dislikes the sci-fi genre and things with robots and AIs, I was honestly very interested by the story because I couldn't really tell who the person they were looking for really was. Like you don't realize that there's more than one blue-eyed AI until like midway into the story, and then you realize after they find one blue-eyed AI, they have to find another, and then there are some really interesting plot twists.

There are a lot of parts where they also focus on friendship (cries) and family issues of the three main characters, and I think those were really nice moments in the story. It's cool that the characters get mad and angry (like any teenager) but they also learn to forgive and forget. Plus the story got really emotional towards end, and I was really surprised by it, but a good kind of surprise. 

And the ending......oh my that was so sad and touching!! I think one of the cool parts about this webdrama is that it brought up and explored a lot of aspects and questions and ideas regarding Humans+AIs that humans should consider as technology continues to advance so quickly,  especially if more AIs and robots start to appear in the future.

Acting:
This is TFBOYS first acting gig for an actual drama, so they are all quiet inexperienced since they debuted and are still singers. But they were pretty decent for first-time drama actors. I'd say out of the three boys, Junkai had the best performance. His two emotional/crying scenes (especially his very last scene!) were really good for his level of skill and age. Actually cried real tears at the very last scene of them three together.

I do think the adult actors, were quite lacking. Some of the adult ones were okay, but some were actually pretty bad/awkward actors. Also, most of the actors in this drama have pretty poor Mandarin pronunciation and enunciation; I would've preferred it if they had been dubbed to be honest.

Music:
I'm pretty sure all of the OST songs were TFBOYS songs, so I really liked the music (since I'm a fan of them)!! Especially the main theme song ???????is actually one of my favorite TFBOYS songs.

Rewatch Value:
I might rewatch some of the friendship scenes and the scenes where only the TFBOYS were in and having fun as a group of three. But I probably won't really be rewatching this drama. But it IS only 15 minutes each episode, so it's very easy to rewatch if one wanted to.

Overall:
Came in with low expectations since the actors were all so young and inexperienced, and I didn't like the genre. But surprisingly, it was pretty good and enjoyable!! Personally think that if this story was remade, with an even more extensive plot (I like the plot already of them trying to figure out who were the AIs) and older actors, and they kept the topics and ideas about Humans+AIs that were explored in this webdrama, this could actually be a pretty good scifi drama.

Final Disclaimer: I do like TFBOYS though, so the rating could be a bit biased. I might change overall rating to like a 7.5 later on, but currently I'm still in the moment, and I thought it was a really enjoyable webdrama.
