Male A and female B love in the ABO world.
The heroine Lu Shuning is a genius among geniuses. She was admitted to the Central Military Academy at the age of 17. The hidden technological spire in the academy. Perspective: I had no intention of getting married, but the mastermind forced the marriage. Fortunately, I was given the right to cancel, but why did the cancellation fail every time? ! If you fail, just fail. As long as it doesn't affect your research, it doesn't matter if you have an additional identity... Don't come here, you!
Male protagonist's perspective: A secret love that had no chance of seeing the light of day, but because of the arrangement of the mastermind, you became my wife. I originally planned to go against my will to prevent myself from hurting you who are too fragile. Now other APLHAs may hurt you, so why not let me be your shield? Maybe you will like me who is a bit possessive...
Friendly reminder: The male protagonist appears very late, incredibly late...
Intention: I love you and I am willing to follow my heart
