• Structure: 向こう is read as むこう and is a demonstrative noun for a place away from the speaker or beyond a boundary, extended to mean the other party.
• Basic usage: Use 川の向こう for the far side of a place and 向こうの返事 for a response from the other party.

2. Common pitfalls and similar expressions

• Place and counterpart
