Zuhören ist die beste Kameradschaft

Missing, extremely new, or very obvious to obtain.

Let her/him/them cook is a slang that means to let someone do something they’re good at. In this chive’s case, let Hanya yap all she wants. The Chinese version, 聆听是最好的陪伴, which roughly translates to "listening is the best form of companionship." It more or less talks about the value of listening in relationships and emotional connections. Truly listening to someone, giving them your full attention and understanding, is one of the most meaningful ways to offer companionship and support (to Hanya).
