Nettles a solid 2. She can be afraid of rejection, but generally if shes rejected then whatever. she got the thought off her mind, and can return to her work.

Orchids about a 5? She doesnt handle it well, but she'll get over it fairly fast
Astras like a 4, doesnt handle it all that well but forgive and forget or whatever. Shes already spent liek a decade pining
