Can anyone explain the hairpins? When she got all of them does that mean she is their assistant also?
from an earlier of my comments.
"The hairpin is used by the recipitent to call out the give and they have a secret 'meeting' of course MC takes 'meeting' as escorting so she can go home but it was originally used for secret tryst."
His hair pin that he pulled off in ch 9, my guess it my be a family hairpin based on what his assistant acted since its 'His' hairpin that he 'hid' though in the LN I totally forgot about it since I wrote it off as MC did. might be a manga bonus or will end up in the 2nd arc.
Is there a novel of this?
Yes.
Can you give us the link?
Sorry I don't have a link but someone just recently is going to start translating it soon.
