Yeah, if you pay attention to the dialogue, it sounds like it can just be two close friends giving each other chocolate or it's one-sided on Genji's part. But it seems like Blizzard is REALLY trying to push for Gency right now. Either way, I'm disappointed, but I'm not angry. If there IS something I'm mad at, it's Blizzard's poor way of not letting the audience know sooner so that the backlash could at least be somewhat less hostile and outraged. It's been a pain in the ass--on both the pro- and anti-Pharmercy sides--to deal with.
And yeah, there's a lot of "TRACER'S NOT GAY" stans celebrating the fact that Genji and Mercy are giving each other chocolates. Ugh...really lets you know what kind of people they actually are.
