The young man is not a flaw left in the New World by the Old Era.
This is not favoritism. When opening up the Tianhe, the young man had already burned away his own Old Era timeline record; he has no "any" relation to the Old Era anymore.
Yet what the young man wants is still the best future for the Tianhe people; when what he wants conflicts with what she wants, it spawns a heap of undesirable future paths, ones that belong to "mutual destruction."
Tia can see this deduced future, so can the young man, but his self is incomplete, his cognition is missing, and his attention is more focused on the current chess game, thus the irrelevant parts are blurred.
Blurry does not mean nonexistent; when his self becomes complete, he can also see a clear future path.
This match won't stop just because Tia sees many "mutual destruction" future paths.
