If you have to be heartless, learn Buddhism. Color is empty, and color is color.
Therefore, gas is colorless, eyes have no ears, no nose, no tongue, no body, no fragrance, no ignorance, no old age, no pain, no wisdom, no income, or everything that has a way is like a dream, such as dew and electricity.
Love is the same, just an illusion, a feeling. Then it won't really exist.
People fall in love for the same reason as animals in heat. Hormone secretion and male and female attraction are quite low.
