heart react

/hɑːrt riˈækt/

Very Common

Reacting to a message or post with a heart emoji, signaling warmth, affection, or approval.

Less intense than a fire emoji. A heart react often signals genuine warmth or affection rather than obvious attraction. In close relationships it can read as intimacy. On a stranger's post it can still read as flirtatious.
