YEP!
The senpai shrine.
This will include the following:Gum
Crushed cans
Toothbrushes
Pens
Food
Trash
Locks of hair
Parts of clothesThis would do great.
The main thing you want is a picture if Senpai.
This is why stalking is important.
That way you get this picture.
You want to get the pictures when he's not looking.
If he sees you, it may lower your chance in getting his love.Good Luck
