Basically beggar decided to fuck with a lot of characters personalities and Sarah went from sweet little sister to oblivious semi bitch plus Christian and Sarah's interaction are leaning more or less to you getting cucked
Which was dumb, he already had a good combination of personalities in the family... Step-mom and middle sister were bitches to the MC, Oldest sister was kind and caring, and Sarah (little sister) was sweet, and fangirl-ish... Why make Sarah into a bitch like Amy ? So whats Amy going to do now ? still be a bitch to cuck the MC from two different sides ? Already the story is developing differently than what it was originally...
It would have been different if he restarted the SAME STORY due to mechanic limitations with the engine, or coding he could no longer fix... (memory leaks etc)... But restarting it just cause he NOW envisions the story differently ? WTF...
If the MC gets cucked left and right with his family members in the new story, I am never going to believe he ends up being the badass that won the fighter's championship later... especially if his personality is confident badass during some story segments, and doormat loser during others...
