Anyway, I feel rather proud of myself about getting all five good endings without guides.

Anyway, what I was going to ask was... From those of you that got the good endings on the first go... Was it worth going for bad endings afterwards? I won't mind reading about the bad endings, but going through them doesn't feel right. I'm currently at 94% completion, and I'm thinking of leaving it like that. No extra scenes unlock after 100%, right?
PS. My opinions about the various characters and story arcs:
Favourite character: Hanako
Favourite story arc: Lilly
Saddest story arc(s): Lilly/Rin/Shizune(though that was mainly due to feeling horribly sad for Misha. That rooftop scene really punched me in the gut.)
