The story was compelling and the relationship between the two main characters as they grow towards each stop they make on the destination. The stakes getting dangerous by the minute and become close throughout the story makes the ending even more satisfying. The lessons you learn is worth the watch.
The diversity made it even better.
You get to know characters and understand motivations and how things turn out. You see all aspects of sexuality and races.
It’s not a cookie cut anime story line but it shows heart and really touches on the emotional strings. With 22 episodes I recommend it.
