She's the worst sleuth, period.
Anyways, 90% of the time characters who do that don't become likable, or at least popular. Panicky, overactive imagination(in the unfunny way), can't make up their mind and extremely nosy.
Been a while since I have found a chapter in this that I thought was not even at minimum a decent read. This kind of felt like it should belong in an extra or omake.
Not a new thing to see somebody nosy about if somebody has a girlfriend/boyfriend they don't know of, but usually they go about it in a funny way.
