Guy sprinted harder than an athlete just to walk a girl home

A girl is telling her story: She was at the mart and walking behind a group of 4 guys who happened to be going the same direction. At an alley, 3 of them said bye to the one going a different way and kept walking — and she was still trailing behind all of them.

Suddenly, one of the guys goes 'Oh no this won't do' and announces he'll escort her home. Sweet, right? Except then that same guy immediately BOLTS full sprint down the alley to catch up with his friend who split off earlier.

So she was left standing there watching this dude run like his life depended on it — all that chivalry speech, then zoom. She was stunned speechless (설렜음 = 'my heart fluttered' but delivered deadpan after witnessing a man literally dash away from her).
