Looking for a BL manga: I don't remember much of it but I'll try to write down what I remember. It's a poly relationship tho.

There were in a military of some kind
MC has a high position in that base
Two ?wolf? like guys who take an interest to the MC, one has long white(or blond) hair and the other has black hair.
They planned to kill MC in the beginning but decided not to because they fell in love eventually.

Could anyone help me??
