At end he (dying) admits that he was gay. Boy answers: we all knew that, written on your forehead

Hello,
I once watched this film in hungarian translation and it took huge effect on me, but since years nobody can help me to find.
I dont’ know the exact plot, but at the end, before the adult man dies he admits that he was gay. The boy who became his friend in the whole film answers: oh, we all knew that already, it’s written on your forehead. And the man passed away so calmly that they accepted him as he was.
May you help me if you have seen this film and know the title?
Thank you in advance.
Thomas
