My Heart Beats (2023)

Heartbeat is not a BL, but it has the same trope of vampire sleeping in a coffin for 100 years and vampires doing magic rituals to become human again. Also this retinue the main character has is even visually alike to that of Heartbeat main. Even the ridiculous haircut is similar.

The female leads of both shows are humans. While the male leads are vampires (well, Heartbeat's male lead is specifically half human half vampire)

It focuses on a naive, loudmouthed teenager named Rion, who investigates a host club full of vampires when she suspects they must be related to the disappearance of a lot of people in the neighborhood, including her best friend. In the process she begins to befriend them, especially the leader Suou, with whom she develops a romantic relationship. Ultimately, she figures out the vampires are not the cause of the disappearances, but her adventures with the vampires are only beginning
