[Show-Off x Cold and Detached]
A second mutation reshuffles the balance of power.
Yao Tianguang awakens a useless ability, only to find everyone in the world stronger than him. Just as he's getting upset about it, he discovers his nemesis, Wen Su, has it even worse: coughing up blood every three steps and passing out every five.
Both are kicked out of their organization. Yao Tianguang mocks him: "Your face even changed after you awakened. Why do you look like a sickly old man?"
It isn't until their first trip into an S-rank contaminated zone, after they make intimate contact, that Yao Tianguang realizes the person beside him might not be human.
After dying once and coming back to life, he belatedly realizes that he might not be human either.
During one mission, Wen Su is badly injured and shrinks back to his adolescent self.
The good news is that his body works better than ever, and he finally stops coughing up blood. The bad news is that Yao Tianguang's body can't take it, and he nearly bleeds several times.
For years to come, rumors run rampant, with everyone saying that Yao Tianguang awakened a pregnancy ability and secretly had Wen Su's child.
The stories grow more and more outrageous, becoming the ultimate version of a forbidden relationship.
Yao Tianguang's face darkens when he hears them. So these people are turning everything, whether good or bad, into something dirty???
_
One day, Yao Tianguang catches Wen Su being a pest. "Call me Dad."
Wen Su remains perfectly calm. "Daddy. Can I come into your room tonight?"
Bystanders stare in shock. Holy crap! A father and son in this day and age???
