I've been looking but I just can't remember the name of this yaoi:

Its in a military setting, and there are two main characters - a prisoner from an army and the military person in the opposing army watching over the prisoner . As per usual, the military person of the opposing army makes a big show of abusing the prisoner, but they are actually past lovers/friends. There is a happy ending.

Thank you for your help!

i think i know what you're talking about but I can't remember the title either (i'm terribly sorry.) i read it so long ago and it's deep within my list (which i have searched a bit.) but i'd like to know the title as well!

...

Your description made me think of Giglio but it probably isn't what you're looking for.

Oriolidae & Sparviero

Thank you so much everyone for your help!!! 😀

I realized I was actually thinking of two mangas (lol) - one was General Dandy, but I couldn't remember the other one. Raeryn got it, it was Kyokutou no Hanamuko - Raeryn, you are the awesome!! And thanks for the great recommendation sparviero-92!
