Meaning
Two pink hearts of different sizes floating side by side. It is light, sweet affection, a little like a doodle in the margin of a note, used between partners, close friends and family alike.
It is a natural sign-off for friendly messages and a soft reaction to cute photos: “See you at brunch, love you guys 💕” Many people use it more casually than the red heart, so it rarely feels too intense. Repeating it after every line, however, can make longer messages look cluttered.
