The protagonist opens her eyes to find out she's been reborn as a spider. Which is already nightmare mode, before having to worry about cannibalism from other spiders, not the least of which being her mother! The story of a high school girl with  nerves of steel and her struggle to survive in another world begins here!
Shun is just showing her 
the respect she deserves.
يمنحها شون الاحترام الذي تستحقّه فحسب
Shun zollt ihr nur den Respekt,
den sie verdient.
Shun est poli avec elle, voilà tout.
ed è per questo che Shun le si rivolge
con rispetto. Tutto qui.
O Shun só está mostrando
o respeito que tem.
поэтому Сюн относится к ней с уважением.
