[Ginrai]

Question on two of the Katsura endings for the game:

Spoiler:

In the one where Makoto rushes to Katsura's defense against Otome and her friends, what was he telling them? What was he talking with Sekai and Nanami about? And what were Sekai and Nanami apologizing about later on?

In the ending where he brings Katsura lunch after Otome's friends ruins hers, did he realize that she was being bullied? What were the girls telling Katsura and what were they discussing afterwards? Hikari and Nanami also looked rather angry when he was talking with Katsura at the station; why was that? Also just what were Katsura's sister and mother discussing at the beginning and end?
