1)Hmm,Im tied up between the twins and Jun,I would love to see how maybe a relationship starts to form between them and how Leo and Griffith will act.Also i would love to see Juns route cuz him and Rei have alot of backstory behind and them to have a fresh new start and see how things work and if Jun will change for Rei so he can be with him again,also i will play all of the routes anyways :))) bu tmy opinion of everyone is like pretty neutral mostly Minami cuz im not really for that kinda type of characters in VN but in the same time i dont want to kill him.
2)Hmm...will the cat be apart of the story's too,like not having only one or two interactions.Also does Minami will become a yandere?
3)i read them,i think that they dont really in my opinion raise any spoilers atleast for me.
4)hmm i think the GC's will be enough.
5)probably Jun :)))))),because he still has feelings for him.
