is the extra supposed to have happened before the end ? Because the seme seemed confused about his feelings when he asked his friend about kissing and all. It's confusing because usually 6.5 means extra happening after chapter 6 but from the plot, that doesn't seem to be the case (?)
@Akera93 yes, this extra is named 2.5 because it happens after chapter 2, but since it's placed at the end of the volume, I had to numbered it 6.5 so it doesn't get misplaced by mangadex's system.
