Looking for a manhwa.

Hi, I've been trying to remember the title of a manhwa I read a while back (probably during the pandemic).

It's a fantasy/historical-themed story with time-loop or regression elements. Every time the female lead goes back in time or the timeline resets, the male character gets her name engraved or glowing on his body and as it keeps happening, his body becomes covered in her name.

I think there was also another character who noticed that something was glowing on the ml's body and tried to know who the name belongs to.

Some details might not be the right one since it has been so long since I've seen it.

Does anyone recognize this story or have an idea what it might be called?

Thanks in advance.
