You and I are already "strangers," aren't we?

This is a light work. 6/16 Thank you all for your feedback. 　　　I added some sections where the explanation seemed to be lacking. 　　　Also, thank you for reporting the typos. A woman who claims to be the girlfriend of a man who was my fiancé, but is now someone else to me, came and told me to "release him." Even though I explained things to him in front of everyone, did nothing get through to him at all? Does he think my words aren't worth listening to? I wish he would stop making a fool of me.
