>>30924289The one closest to canon is Brendan and May (player characters from ORAS) as there are a lot of hints, with you going out with them to see a meteor shower at the end of the Delta Episode, which could be assumed as a date.
In the manga (which, by the way, I know isn't the same canon as games) it is outright confirmed and both of them confess to each other but nothing more is brought after that.
Other ones close to canon are:
Nate/Rosa and Yancy/Curtis (sidequest with the Xtransceiver in B2W2. After a lot of calls, they start blushing when they talk to you.)
As you mentioned, Calem and Shauna. (I prefer Serena but she didn't have much hints, if at all)
Sun/Moon and Lillie. The dialogue changes depending if you play as boy or girl like in XY.
Another one is Dawn and Lucas but those two don't have much beside a few vague hints. I expect the remakes (if they do come out) to do something about this.
