Often in fiction the person who you have the crush on lives right next door. Comes in three types.
- The protagonist and the neighbor fall in love with each other.
- The protagonist loves the neighbor but they don't love the protagonist back. (Possibly because they're unaware of the crush.)
- The neighbor loves the protagonist and they most likely know, but just doesn't feel the same way.
This neighborhood love interest can overlap with the Girl Next Door who is average and wholesome femininity personified. He might not be able to resist the urge to take advantage on the situation and spy on her or he might visit her by Enter Stage Window.
Obviously, not really that rare in Real Life. It's been said that one of the more unusual side effects of the steam engine was that for the first time people weren't limited to marrying their neighbors.

- One-sided example in Saber Marionette J. Hanagata clearly had a thing for Otaru, who despised him, from the get-go, but it's not until he gets a fortune-telling that spells the trope almost verbatim that he gets more blatant about it.
