Something like this I guess
Hibiki left home to realise her dream and decided to not return to or stay in touch with anyone from Okinawa before she does.
P learns that Hibiki is actually very lonely.
Hibiki slowly learns the value of friendship and bonds and she makes up with Alisa, an old friend back in Okinawa.
This...vid...is not making any sense to me...
Although they seem to be talking about the IA Awards and being competitive...
Thus we're now here.
Touma heard Hibiki talking loudly in her phone in a nearby park and told P.
Hibiki's calling Alisa, blurting out stuff that shouldn't be known to the public yet and she does it with a loud voice so that anyone nearby could hear it, thus risking cancellation of the IA grand finale.
Tsundere Touma doesn't like that and leads P to Hibiki.
*Insert standard random angry Touma remarks towards Hibiki here*
Touma leaves.
Hibiki leaves to resume her call at home and she'll leave out unnecesary stuff and she'll be more quiet.
With the power of her bonds she defeats Jupiter eventually and everyone's happy.
P leaves for Hollywood, Hibiki decides she should go back to Okinawa for a while.
And.. BT2P didn't see the good ending and is stuck here.
