Looking for a manga

[Ranzo]

For the life of me I can't remember what this manga was called and I'm not even sure if there were more updates to it
Okay so basically the manga was about a high school guy who wakes up one day to find out that he's suddenly dating this popular girl and that he apparently saved her from some perverts.
He can't remember this happening at all, oh and apparently his father was a serial killer?

This is what the girl looked like if that helps

I feel like you just spoiled a major plot point lol

It's like in the first chapter so only a little bit

@Ranzo I think it's this one...

Edit:
A bit curious how people directly tag the manga.
