I recommend the following two novels to you: 1. Owe Him a Kiss: The Alsatian reunites with the idiotic senior in a bar. The male protagonist had once forced her into the bathroom, but when they reunited five years later, the female protagonist had already forgotten about him. 2. "First Memories": Two strangers reunite in a bar. They start to recall the past five years ago and gradually fall in love. I hope you like my recommendation, Mwah ~😗
