[Emotionally Deficient, Spacey Humanlike Bot Bottom x Obsessive, Paranoid Stalker Top, 1v1, Happy Endings in the Individual Worlds]
Sang Shuo works for the Space-Time Administration. Because he was born with little capacity for emotion, every world he visited collapsed due to one mishap or another. To protect his performance record, the System's central office assigned him to enter different worlds as a villainous cannon-fodder character.
He understood. Villainous cannon fodder characters were all malicious, sinister, and full of schemes.
[World One]
"You're a yandere.
You used underhanded methods to lock the protagonist bottom in a basement."
According to the plot, Sang Shuo would be hopelessly in love with the protagonist bottom and would even hurt himself to win the other's sympathy.
He would try to get intimate, then, when rebuffed, break into a lovesick, satisfied smile. Eventually, the protagonist top would find him and give him a thorough beating.
He messed up on the very first step: he kidnapped the wrong person.
The gloomy boy in front of him was the protagonist bottom's younger brother. He looked almost exactly like him and had said nothing since being tied up. Sang Shuo wasn't interested in him and was about to let him go, but the boy clutched his clothes tightly.
The other boy nervously held on to him, his eyes blazing with unmistakable excitement and delight. In a small voice, he asked, "Can you just kidnap me instead?"
Sang Shuo: Why isn't he running away? (confused)
System: ... (He's even more messed up than you.)
[World Two]
"After your husband, who is twenty years older than you, dies, you inherit a huge fortune."
In the original plot, Sang Shuo made off with all the money, kicked his husband's only younger brother out of the house, and spent his days living it up.
But in reality, an extra clause had been added to the will: he became his husband's younger brother's guardian.
The boy was two months shy of turning eighteen. Living under someone else's roof, he was obedient and well-behaved, always quietly trailing after Sang Shuo.
That was what Sang Shuo thought at first, until he accidentally caught the other boy lifting his shirt to take a photo of his still-damp, defined abs.
The next second, a new message from his online boyfriend arrived on WeChat.
Sang Shuo: Should I tell him this is a bad angle? (thinking)
System: ... Maybe you should kick him out after all.
