The term "friends with possibilities" describes the situation where you start out as friends with someone, but have the possibility or potential for a relationship on the next level.

Friends with possibilities指的是你跟某人开始只做普通朋友，但有潜在可能会朝着建立恋爱关系的方向发展，我们可称为“可能成为恋人的朋友”。

这个说法大概是从那部名叫《Friends with Benefits（朋友也上床）》的电影演变而来的。

For example:

"Are you two dating yet?"

"No we're just friends with possibilities for now.”

“你们俩在恋爱吗？”

“没有，我们现在只是普通朋友，不过可能会朝那个方向发展。”
