None of this was a coincidence, that's what Jimin is feeling.
The universe feels different today, just from Taehyung's happiness. Jimin always waits for Taehyung's call, and that's how it will always be.
Even with how Jimin's heart flutters, he feels afraid. Fate seems to pull them apart, but they still persist.
The universe seems to move for them. There's nothing out of place. Their happiness with each other was expected, because they love each other.
Taehyung is the one who saved Jimin from his darkness. Taehyung is his angel, his world. All Jimin wants to do is love him.
When the universe was first created, everything was already decided. Their fates were already intertwined, and it will forever be.
