I'm looking for manga and novels with the following plot:

1. The story starts off with the protagonist having amnesia.
2. A few people claim to be the protagonist's lover/fiancee/etc.
3. The story slowly reveals the protagonist's past.

The protagonist can be either male or female.

The Indecent Relationship Between Four Lovers (Novel) is one example.

"You are weak, from the moment you could only use your life as an excuse for committing crimes, you insulted that very life. You didn't notice, you were afraid of noticing, and you went around destroying everything that could make you notice, but you have also crushed your ability to ever gather respect." -Shokuhou Misaki

Otomate x Idea Factory's AMNESIA series are exactly what you want (unless you don't like reverse harems).

In this story, the heroine finds herself with no memories and 'trapped' in a kind of time loop which sends her to a different version (world) of the morning of August 1st every time she dies. In every different world, there's a different guy she knows who claims to be her lover.
In order to recover her memories and understand why she's trapped in this loop, she will have to interact with them and discover some secrets.

The cons: none of the volumes are completely scanlated in English ?

1. AMNESIA 1st part
2. AMNESIA 2nd part
3. AMNESIA Later Comic Anthology
4. AMNESIA Joker
5. AMNESIA Crowd
6. AMNESIA Later New World

As an alternative, you can watch the anime version. It has 12 episodes.
