[Reader's Guide]: 1. One-on-one romance, both leads have only ever been with each other, happy ending. 2. Not a traditional substitute romance: the person in question is the same all along.
Lin Xi, the last transmigrator, bears the responsibility of repairing the cultivation world.
But his stingy System gives him no spiritual power, and instead makes him earn points by protecting the cold-faced senior brother, Wu Hanfeng, which he can then exchange for rewards.
Wu Hanfeng calls Lin Xi a good-for-nothing and accuses him of cheating. Lin Xi puts up with it all because he's timid and good at keeping his head down, taking his people-pleasing nature to the extreme.
Until one day, Wu Hanfeng corners Lin Xi in his room and asks whether he was the one who saved his life as a child.
Looking at the quest in the System that he still hasn't managed to complete, Lin Xi answers without batting an eye: "Yes. It was me."
Using this identity, he enjoys Wu Hanfeng's protection and resources while completing his own quest.
All the while, Wu Hanfeng is torn. He's certain he's found the person he's looking for, yet can't bear the thought of his hopes being shattered.
But people always come around, and Wu Hanfeng is no exception.
So he changes his attitude and begins to accept Lin Xi's little flaws. He even decides they're not flaws at all, but rather part of his charm.
As Wu Hanfeng's affection gradually takes hold, Lin Xi lets down his guard, and even finds himself a little jealous of that "white moonlight."
