キュンとする

• Reading: キュンとする
• Romaji: kyun to suru
• Pronunciation: /kjɯɴ.to.sɯ.ɾɯ/

Meaning

A heart-fluttering, swooning feeling — the sweet pang of romantic or emotional tenderness.

キュンとする describes the specific chest-tightening, heart-squeezing sensation triggered by something adorable, romantic, or emotionally touching. It is strongly associated with romantic moments — a confession scene, an unexpected kind gesture, or watching a cute couple. The related noun 胸キュン (mune kyun, chest flutter) is a genre tag for romantic media. While predominantly used by women, it is increasingly used by all genders.

Examples

1. あのドラマの告白シーンでキュンとした。 That confession scene in the drama made my heart flutter.
2. 不意に手を繋がれてキュンとしちゃった。 When they suddenly grabbed my hand, my heart skipped a beat.
3. 子猫があくびしてるの見てキュンとする。 Watching a kitten yawn makes my heart melt.
