SA：If you do move through the space of another creature— whether a friend or an enemy—the space is difficult terrain for you, and you can’t willingly end your move there.
PHB：You can move through a nonhostile creature's space. In contrast, you can move through a hostile creature's space only if the creature is at least two sizes larger or smaller than you. Remember that another creature's space is difficult terrain for you.
Whether a creature is a friend or an enemy, you can't willingly end your move in its space.
lfyou leave a hostil e creature's reach during your move, you provoke an opportunity attack, as explained later in the chapter.
结论：我认为你会被挤出去，但是二者其实都没有写明白。
