Post a female character displaying stalkerish behaviors/with stalkerish tendencies as well as spying on a male character

Sacchan from gintama X3

The parte superior, arriba ninja of the oniwabanshu always stalking Gintoki but no matter how great of a ninja she is Gin-chan can always spot her XD

Juvia (Fairy Tail) is often seen stalking and spying on Gray.

Megumi Shimizu, in Shiki, often spies on Natsuno from behind a bush.

Touko Fukawa from Dangan Ronpa
She absolutely adores Togami ^^''

Yuno Gasai

I can't find any screencaps o clips of the actual spying in progress.

Sana from Kodomo no Omocha spies on, stalks, bullies, & blackmails Akito (because she's a total spaz who likes to stick her nose in other people's businesses). She eventually starts to warm up to him after she finds out he had a shitty childhood. He falls for her after she shames his family, but she does not return his feelings at all, at least as far as I've gotten.

Hinata Hyuuga (Naruto)


Hinata stalking Naruto.......he he he he

In episode 8 of Qualidea Code, Asuha Chigusa stalked her brother Kasumi upon seeing him with Aoi Yaegaki.
