告白するヒロインを間違えてしまったモブキャラの俺、気づいたらヒロイン達に好かれていた件

I was reincarnated as a background character named Haruya Hayakawa in a certain gal game. I was supposed to confess to one of the heroines, Reina Shinohara, as in the original story, and get rejected… However, when I appeared to confess, the other heroine, Saki Hinamori, showed up. After that, I got rejected by her. Even though the person I confessed to was different, I still achieved the original role of being rejected by the heroine… or so I thought. That’s what I believed, but then an unexpected turn of events happened…
