>>1982583 I don't want to get into this too much but a girl who is 17-18 is not a loli, by definition. She also does not have a child's body, she is diminutive with a flat chest but it's made clear (and explicitly stated repeatedly in the LN's) that she has a figure that cannot be mistaken for a child's.
Although I guess you did say it make you a lolicon, which would still be accurate if we're assuming you got a taste for things associated with lolis that do apply to a legal adult in this case but are loli-like such as being tiny.
