Minor spoilers! The first few episodes were really messy in my opinion, but it got less messy as the story progressed. Though it overall just felt unrefined. To start off, a lot of scenes were unnecessary or waste of potential. They really could've made it simplier for themselves by taking out scenes that won't be continued or talked about later on. I just ended up wanted to edit this series like a youtube video, if you know what I mean. When you start rambling about stuff that doesn't actually matter, but you get distracted. That's the type of feel I got from it. Don't get me wrong,the story is cool and all. It would just be way cooler and better, if it wasn't so messy.
There was a, let's say, vulgar scene and it felt all too natural between the two involved. He gets a sort of "punishment" later, but that gets fixed by the victim?? There's also this backstory of the victim that I really don't get it. That backstory was all too long and unnecessary for an excuse not to trust the mc, but that only got used once?

The art style is an average chinese anime. Like I don't really know why, but all chinese animes has the same style. At least those I have watched, like King's Avatar has a similar style.
Really nothing much to comment about, just a average anime style I guess.

I really don't remember soundeffects and the opening song/ending song. It wasn't all that memoriable. I do admit that I listened a little to the ending song everytime though. It amuses me to see survivor anime characters play in a band in the ending song, yk?

I could honestly go on and on about the individual characters, but I'll do a brief overall view. Mostly because I really don't remember the names of any of them, didn't stick with me.
To say the least, the characters are flawed. I feel like some of their actions were just to prove a point in the characters backstory. Though I will say that I hate none of the characters, which is rare when it comes to survivor animes. Some characters were annoying, but let's say they were taken care of.

Overall it's an anime that's not finished. It's one you binge watch and in the end wishing there was an end. One you'll probably won't remeber watching the next week. A year from watching it you could watch it again and feel as if you recognize it. That kinda anime, yk?
I would say, give it a try.
