A person who only likes others for their appearance is often referred to as superficial or shallow. Being superficial means that they prioritize and value physical attractiveness over other qualities or characteristics. Such individuals may not take the time to get to know someone on a deeper level or appreciate their inner qualities, focusing primarily on external appearances.
It's important to recognize that valuing physical appearance above all else can lead to superficial and potentially unsatisfying relationships. Meaningful connections and lasting friendships are often built on understanding, empathy, shared values, and mutual respect, rather than solely on looks.
