I started watching it because Yamada Yuki is part of the main cast. But the plot of the series is interesting and well-thought of. Definitely worth a watch and rewatch all over again. Track by Official Dandism (Tattoos) made it all more interesting. 💯 Highly recommended series ~
[Although the only thing I don't like about it is the happy ending for one of the survivors who is a cheater 😑]
