Help finding a manga

[wagnerjr]

It's about a guy who transferred to another school. And in this new school there's a mysterious girl who knows about the 7 mysteries that exist in this school. The MC falls in love with her and to win her over he must discover these secrets.

I remember a part where they enter a tunnel and go to another world. And when she adopts a dead cat, or the spirit of a dead cat

@wagnerjr Sorry this is not an answer. I've browsed through Transfer student tag with supernatural genre or supernatural element tag on manga updates and didn't find what matched your description. Granted, not all manga are properly tagged. So, do you remember a little more details of this manga? Story events? Is the supernatural element strong? Any more physical or characteristics traits of the MC and female lead? Also do you remember where you read it? Occasionally people were looking for locally published or non English-translated manga and it could be quite hard to find it online in this case.


Ps: I'm also intrigued since I like school supernatural mysteries stories. Will definitely try to help you find if you could provide more identifiable info.
