After My Boyfriend Lost His Memory, He Fell in Love with Someone Else

My boyfriend lost his memory.

He erased me completely from his memories, forgetting everything we shared. He despises me, sneers at me, and humiliates me in every way.

I thought that as long as I didn't give up, one day he would remember. But then he fell in love with someone else!

It shouldn't be like this!

I'm the one he loves. We were already about to get married. Why did things turn out this way?!
