I think the family/friendship routes are meant to supplement the story and character development, unravel more mysteries, and depict the characters' untold experiences and emotional changes.
In *Code Realize*, Finis makes it clear to the player that he's not simply hindering or opposing the female protagonist; there are underlying reasons. He desperately craves fatherly love, but his father treats him as a replaceable substitute and uses him. The fact that he and the female protagonist are twins is a plot point only found in individual routes. His feelings for her are somewhat conflicted, unlike those of typical family members, and both are androids. I consider his route as supplementary explanation, a purely family-oriented route, not a romantic one.
我覺得家族/友誼路線是為了補充故事和角色設定,解開更多謎團,描寫人物不爲人知的經歷、感情變化。
《Code Realize》中的Finis讓玩家明白:他不是單純阻礙女主角、與她作對,背後都有原因。他非常渴望父愛,但父親當他是隨時能取代的替換品、利用他。他和女主角是雙胞胎,也是個人路線才有的線索。他對女主角的情感有點矛盾,不像平常家人,而且都是人造人。我把他的路線當作是補充說明,非談戀愛路線,純粹家人路線:眨眼:
