Jealousy
Billy's plan to make Ronan and Roselyn jealous of Billy and Sarah fails. The two humans, instead of stretching, were now sticking together even more.
Of course, this made Billy and Sarah disappointed. Even though they had been acting desperately, the result was nothing.
"See, Ronan can't take his phone off at all." Sarah pointed at Ronan, who was laughing on the phone with someone on the other end. Who else was Ronan calling if not Roselyn?
"Yes. I saw it," Billy said unenthusiastically.
What made Billy even more disappointed was that Roselyn had secretly asked for Billy's number at the end of their meeting during a double date at the butterfly cafe.
Billy's reaction when suddenly asked for his cell phone number was, of course, shocking. He even thought he was hallucinating because he missed his orphanage friend.
