I'm looking for a manga between a girl spirit and a high schooler/middle schooler (Can't remember which) girl. I can't remember why the spirit stuck with the student, but they became good friends either way. Also, the spirit is in charge of bringing people together and connecting them with a "string" (like how there's a red string to indicate someone's meant to be with someone). I also think there was another girl spirit that was in charge of severing ties between people (cutting the string) and that spirit also had a girl student buddy.
I can't remember if this manga was subtext or yuri, but I remember faintly that I think there was the lots of hugging tag. Also, the cover photo was the spirit girl sitting on the torii of a shrine I'm pretty sure.
Hopefully I didn't provide an wrong information. Thank you!
