Minerva

I kept remembering this particular scene where the top was jealous because he saw the bottom talking to someone else. It turns out that he was talking to an underclassman that he met during his enlistment.

(I remember the top having a black hair, the bottom had orange hair.)

(Btw. The underclassman always wears a hat.)

I could swear that I remember this science in the manhwa. The title is "why are you so kind to everyone except me."

But the problem is. No matter what platform I look. The manhwa is not on that part yet. But I know that I've read it. Please help me guys.

Please help me find this manhwa. The only thing that I remembered was the girl had a twin? And then they were having troubles on who is the real one. I believe it was Isekai. The girl has white long hair
