Aimyon – Heart [OFFICIAL MUSIC VIDEO]

“Heart” by Aimyon is a song that captures the gradual realization of one’s honest feelings of love.

Released in 2021, it was chosen as the theme song for the drama ‘Only Just Married’ (Kekkon Todoke ni Han wo Oshita Dake Desu).

The lyrics convey the feelings of someone who lacks confidence and often ends up troubling the person they love, yet insists that the feeling of ‘I love you’ is not a lie.
