Disguised as a System After Being Possessed

The protagonist is in a vegetative state. Then, one day, he discovers that he can move! But it isn't because he's recovered. Someone whose origins are unknown has transmigrated into his body. That person uses his body, his identity, and his face, walking around right in front of him. What's more, this outsider has a powerful ability to see spirits. He's not only good at exorcising evil spirits, but can also see the protagonist, his "spirit behind the scenes." The protagonist gets a bright idea and pretends to be a System, giving the soul transmigrator a series of missions. To his surprise, the transmigrator believes him and diligently completes every mission this "System" assigns, taking care of his family, managing his studies, maintaining his friendships, and even helping him rank up in games. His once-messy, utterly failed life begins to shine anew under the transmigrator's careful care. --Maybe it wouldn't be so bad to leave my life in his hands. The protagonist has always been in the habit of despising himself. With no attachments or regrets left, his soul turns transparent and is on the verge of disappearing when the powerful, reliable soul transmigrator grabs his hand, losing his composure for the first time in a panic. Theme: Only by facing life with a positive attitude can you find happiness.
