I'm looking for something I read a few weeks ago but I can't seem to find it, so I hope somebody can help me out. It was a one-shot about two girls who were good friends. I forgot their names but let's call them A-san and B-san for now. So yeah, they were friends but A-san was in love with B-san. I think B-san somehow bringed up the idea of marriage, but I don't really remember this part (though it was probably just for fun). If I recall correctly, it ended with B-san saying that when A-san is getting married for real, she should invite her, since she is her best friend.
