Okay, i have just two question: Is there mom, or someone close (stepmom, someone who the developer can make mom in the future) to this role in this game. And if so - what is her name? I would be grateful for an answer
Mike (the male MC) has a mother named Angela, who only appears in two events if you play as a man, in case you play as Bree (the female MC) you can have a romance with Mike's mother, although I don't think you can have a mother and son harem. The game mentions that Mike has a father, but outside of some conversations and a book he gives you, it doesn't have that much of an impact on the story.
In Bree's case, she has a father who is not very happy with Mike (and his mother), is not a romantic option for any protagonist, and serves as an antagonist. (in my opinion Angela can also be considered a type of antagonist, like other characters)
Half of what is known about the characters' relatives is from anecdotes, and the other half is because they are characters that are a romantic option or secondary, for example: almost all of Mike's family is known except for his father ( that you can only talk to him by phone); Alexis (Mike's ex) and Kylie (his sister); Cassidy, her father Dwayne (she has some scenes with Mike MC and is a possible romance for Bree MC), and her stepmother Cherie (no route of her own); and characters like Harmony or Shiori also have known relatives with whom they can interact, only in specific events of their respective routes and their faces are not seen.
ps I know this part is already out of the question, but just in case I put it
