What's it like to be stuck with a mentally unstable sentinel? From dawn till dusk, he insists he’s from Earth in the distant 790 Galaxy, a sentinel who never remembers to turn on white noise—instead, he begs for hugs when his head hurts. He craves spicy food, then rolls on the ground in pain, pleading for kisses. He tries to hit crowded streets or party at nightclubs, only to melt down screaming Beiyuan’s name. Worst of all, he asks why everyone here keeps a pet—hello, your combat quantum beast is weeping. In short, this is a sweet romance disguised as a sci-fi story: an older sentinel time-travels back to campus, battles a shattered mental world, and still manages to pursue the hot guide teacher next door. Kinda forced marriage trope.
