He Feng, a taciturn and ordinary young man, was involved in a strange system loophole in an accident, and exchanged his life with a "wrong existence" that should not have existed. The originally routine and ordinary daily life was suddenly broken by fantasy. While he has to deal with his disrupted life, he has to manage an "abnormal life" full of surprises for the existence of this loophole. There are no violent conflicts, just daily adventures full of healing. As He Feng got along with the bug, he gradually discovered that this bug was not a pure destroyer. Behind the fantastic phenomena it brought about, there was a secret that connected the two worlds. And beneath his silent appearance, there is also a power that can resolve conflicts and warm people's hearts. In the ridiculous and tender exchange experiences, He Feng not only found a way to balance the two lives, but also gained precious bonds and uncovered the unknown truth behind the system.
