You is a courier, somewhere between dedicated and not-so-dedicated. As a courier, You hasn't joined any large, organized logistics company, but instead wanders as an independent courier.
Terra is vast, and everyone is a wanderer.
You only wants to spend her limited life traveling every inch of Terra.
Perhaps one day, the lone courier will find the people and things she seeks. Or perhaps, when the day comes for her to follow the choice in her heart, she will meet the end that belongs to her.
People keep asking... So let me clear this up: the protagonist is a committed singleton who keeps herself pure. She can be close to people and cuddle with them, but there won't really be romantic feelings or a relationship between lovers.
Also, the protagonist is a native, a native, not someone who transmigrated! And this isn't a gender-bender story!
