Damian Sinclair originally planned to give the downtown apartment to Bella Acker.
As for putting Bella Acker's phone number on the blacklist, it doesn't seem like a real decision to end the relationship; rather, it seems more like he's being petty.
He's mad at her, but even more so at himself!
When it comes to his feelings for her, he's so nitpicky, so worried about gains and losses, so ungenerous, so unlike himself!
Bea talked for quite a while and realized there was no sound from the other end of the phone. She couldn't help but ask, "Bro, are you listening to me?"
"Yeah," Damian said. "I'll handle this matter, you don't have to worry about it."
Bea sighed, "Alright, if you don't want me to get involved, I won't. But bro, I really like that silly Bella Acker. As long as it doesn't involve you, I can still be friends with her, right?"
"That's between you two, I won't interfere," Damian said. "I'm driving, gotta go." With that, he hung up the phone.
