I recently reread Sleeping Moon Nemureru Tsuki 眠れる月by MIYAMOTO Kano 宮本佳野.
This is shonen-ai/BL released by VIZ SubLime originally published in Chara. About a cursed family and the main characters looking to break the curse. It’s got time travel too. It’s historical, supernatural, sf, mystery and drama.
Solid story for BL.
