@Elrahar I was actually confused at that too. Why bother showing them lock the room up if he's just going to leave immediately after?
I also preferred the pre's version of them being in the same class, but I guess this is just to add to her already "mysterious" nature.
@Snowave that would likely be due to the kind of time that's available to work on one over the other. Ero works may only see new chapters twice in a year at Comiket, whereas other common mainstream things are likely releasing monthly, bi-monthly, or weekly.
I can't say I'll keep reading this, but it still bugs me that the title isn't "I Have." I know "I've" is a correct contraction for it, but it doesn't grammatically make sense in this instance.
