Glenn's adoptive mother; their relationship isn't so much strained as it is distantly supportive. He may be a grouch, but he's never rude towards her. He attributes much of his success in the music industry to her enthusiastic encouragement. Neither of them call often, but when they do, they can talk for hours.
Glenn is her adopted child; she adopted him when he was a young teenager, so it took quite a bit of time for him to warm up to her. He holds her in very high regard as an adult, but still has some trouble connecting with her. They both lead very busy lives, so it's not often they get to talk anymore. She still tries to catch his shows when she can, though.
Back when Pina was a personal trainer, Atticus was one of his clients. The two formed a close bond, a friendship that would last for years even when Atticus became busy with his own life and Pina moved onto other career opportunities. When Wynn and Pina had been an item for awhile, Pina and Atticus ran into each other again - it wasn't long before Wynn grew quite fond of Atticus too, and the three began to date.
Half brothers; many people assume Zaiku, the younger, is the more uptight one of the two, but his type B personality makes him far more lax in the long run, even with his rather gloomy vibe. He's certainly more formal than Pina, however, and finds Pina's fake go-with-the-flow attitude insufferable. Even so, they care about each other, and would help one another out in a pinch.
Half brothers; Pina likes to appear calm and collected on the outside, but he actually craves structure and control in his life to a point where any amount of outward zen comes off as a little insincere. However, this is not known by most people, except his half brother Zaiku. The two knew each other from a young age, electing to stick close together while their parents' marriage was strained. Even if they're different and often bicker, they care the world for each other.
