After Losing My Memory, All My Exes Said They Were My White Moonlight

Gu Fan went to a wedding, only to find that half the people at his table were his exes.

After leaving the wedding, he... lost his memory.

Once he had amnesia, all his exes showed up, each claiming to be Gu Fan's one true love.

Gu Fan pulled out a photo and fell into deep thought.

So... who is this person?

I haven't thought up a blurb, so I'm just putting down a premise.
