need the name

Hello my friends, I already asked the same question but nobody answered me. It was a BL manga that I read about two young childhood friends who marry in order to stop natural disasters. On his first night, Seme (I think he has a similar hair as Bakugou) wears a mask and uke (black hair and a little long) gets scared. It was short, I think it was between 1/2 chapters. The art was beautifull. I would appreciate if anyone knows the name.
