Looking for a Dark Romance Thriller Recommendation

I’m looking for books with this kind of vibe:

-Fast paced story

-Dark romance + thriller vibe

-Obsession or stalker type plot

-Story should be crazy and full of suspense

-Heavy dark romance elements

-Very engaging, page-turner (can’t stop reading)

-Easy to understand (not too complex)

-Male main character who is willing to go to any -extent for her

-I haven’t read dark romance before, so beginner friendly

-Prefer something with strong thriller + obsession + stalker vibes
