Akashi is a well-educated young master. He is excellent in all aspects, but he is still an ordinary person and not an omnipotent god (not a cheating character who can predict everything and see through everything).
Kuroko is an ordinary middle school student. His parents are engaged in research abroad, so he lives alone (so there will be problems) stalker jokes, but it is not Akaashi's fault)
The two are better friends than ordinary people, and they realize that each other has an unusual status in their hearts. This incident completely changed everything.
