Koi No Yokan

I accidentally found this term.

Koi No Yokan (Japanese):

Koi No Yokan is a truly beautiful concept. It can defined the sense can have upon first meeting another person that the two of them are going to fall in love. In other words, it is the knowledge one has that he/she is going to fall in love with another person. This differs from the idea “love at first sight” in that it does not imply that the feeling of love exists, rather it refers to the knowledge that a future love is inevitable.

Something I've never heard before. And, yes, it is beautiful.
