After reading all recent comment, I think it's true. The real problem isn't the trauma or anything. It's because they made it a F-ING secret relationship.
If other know they're in a relationship, a sane person wouldn't try to made a move to them.(Ex. The pink guy)
So, f it Jay, just do whatever made you happy. If it doesn't work, just move on, I'm tired of this drama.
So that's the source of their child meme.
