[@Sarcelle Renard] [@EmzyOfNeverland] Since both Hayes and Mark are bartenders and Rena enjoys a night out (and a coffee lol), I imagine she would know them briefly because of it.

[@Ace of flames01] Rena would also know Sophie if the bakery's popular and good. "Ooooh, she's the cute little girl that works at the little bakery in Ann Arbor!" kind of thing. XD And if Sophie's into makeup she would have maybeen stumbled upon one of Rena's youtube videos or her channel.
