Romance anime where MC wanted to date with Person A, but then falls in love and ends up with Person B?

I would really like to see another anime similar to Toradora, where the protagonist wanted to end with Person A, but then he realized the right choice was next to him all that time.

I don't care about the genre (except for gore, i dislike gore) or environment, or if it was a female or male who changed his/her mind.

All I want is that experience of realizing that the right person was next or in front of you all that time.

So far the anime series I've watched that are similar to what I'm asking for are Toradora! and another anime (i forgot the name) where OP chose his "biological" sister instead of his actual girlfriend at the end of the show.

Thanks in advance!
