Sentinel and Guide: Sweeping Across the Stars with a Love Letter System

[One heroine, multiple love interests + Sentinel-Guide + interstellar + sweet romance + all male leads are virgins + male love rivals + sweet-talk System + comedy]

Xu Xingman is a socially anxious college student from the twenty-first century. She never dreamed that the punishment for staying up late reading a novel would be ending up in space as a Guide.

Her new job requires her to counsel and even comfort unfamiliar Sentinels every single day.

A gentle, considerate tulip commander, telepathically linked cat twins, a green-tea fox boy who wags his tail, a little snake who predicts the future and devotes himself to watching over her...

And that sweet-talk System, could you please stop causing trouble? Keep saying things like that and there'll be a fire in my own backyard!!!
