Li Yinhe believes that there are two types of love: one is attraction between opposites, and the other is attraction between similarities.
In my opinion, attraction between opposites is like finding the missing piece that complements each other. This kind of love has tension and is prone to spark, like intoxicating liquor; attraction between similarities is actually like finding a soulmate, another version of oneself in the world. This kind of love is like a lingering taste of clear tea.
Some people prefer to find partners with different personalities, while others prefer those with similar personalities. The former (attraction between opposites) is curious, enjoys understanding others, and is eager to explore the unknown; the latter (attraction between similarities) is somewhat narcissistic, wanting to be understood and craving for recognition.
In reality, these are two extreme situations, and most relationships fall somewhere in between.
If I were to say that the second situation, attraction between similarities, cannot be considered true love, it is more like a relationship similar to that of friends or soulmates. This would definitely face opposition from many people. Psychologist Amas' "Pit Theory" about love actually assumes the first situation, a complementary relationship, and completely ignores the second situation. The following passage can help us understand his "Pit Theory" in a brief and simple way:
When you establish an intimate relationship with someone, you use that person to fill your void. Once the relationship ends, you feel that the thing that filled the void is gone, and you lose a part of yourself. Because the previously filled void is now exposed, that's why you feel so much pain.
According to Amas' "Pit Theory," when a relationship ends, the pain of the first situation is much greater than that of the second situation, because the former is complementary, while the latter overlaps.
