@Jacktris shit, i completely forgot. It been quite long since the first manga. Now that you mention it, i remember she actually look different back then. Now she look exactly like author other work's heroine.
Not only that, she personally also mix with that heroine a lot as well. I just take a look at first manga again and she actually feel like a different character. Now ? I gotta say i can't tell the 2 heroine apart anymore
