Sometimes he will login to the game just to play a map or two, but he will never stay online for longer than an hour...
He will still comment on osu related stuff if it ever comes up in the chat, But he will rarely initiate that conversation.
Every time you feel nostalgic about your rivalry, about the silly waifu discussions, and the late-night deep talks... You will message him... and... he will respond... if... he's still around...
