The first rule of the Undercover Manual: don't become a star within the clouds!
When everyone around you is dark, you should be dark too.
When they shine, you should shine too.
This is what it means to be an infiltrator.
The name Koskao is real; the reason he succeeded is because the real Koskao was already dead, and he replaced this person.
Koskao was noticed by Sedolas's intelligence personnel when bloodshed occurred in Sedolas.
He was noticed because his appearance was very similar to a special agent from Sedolas at that time.
How similar?
The agent sent a photo of himself to Koskao's family, asking how they liked the new clothes he had bought. Koskao's parents responded complimenting his good choice!
To the extent that even Koskao's parents couldn't tell the difference, so Koskao was dead, but a new Koskao was born.
After Koskao's "study abroad" ended, he returned to Peng Jieao, claiming to live independently for work and gradually distanced himself from family ties.
