Dual male leads + equally matched + protagonist is the pursued one + younger man
A 185 cm, eight-pack, pure omega versus a cold-faced young general, an alpha
P.S. The pursued one is no saint, and both leads are powerful.
He was a gangster who successfully went straight alongside his big brother. An accident made him transmigrate to ancient times and become a general. He's a little clever, but not much, and has the self-importance of someone from the modern world. He thinks he can see the whole picture and make things go his way, but in reality, he's just a small piece on the political chessboard.
He is Heaven's favored one, as well as a cold-faced young general feared on the battlefield.
They each serve their own side and are enemies to each other.
He throws caution to the wind, indulges in pleasure, and is shameless; the other is aloof and proud, hot-blooded in his youth, and not what he seems.
Neither knows the first thing about love, yet they are more intimate than any couple.
They get tangled up in schemes, fight each other in their struggle for power, and torment each other whenever one gains the upper hand.
It isn't until one day much later that they understand: love is a desire that takes root in the bones, a heart demon awakened when the soul is shaken, and a possessiveness that exists even before one knows what love is...
So they have been in love from the very beginning. It was simply shallow, filthy, and impure back then...
