Girlfriend witnesses a random crying stranger, gets DESTROYED by it

A KakaoTalk chat where a girlfriend texts her boyfriend while waiting for the bus. She spots two high school girls nearby — one quietly crying while walking, the other seeming a bit awkward about it. She thinks 'oh, some teenage drama' and watches curiously.

Then the crying girl suddenly stops walking and says out loud: *'I told you I wanted you to kiss me before we left school...'* The girlfriend loses it — she did NOT expect a romantic complaint from a sobbing teen.

The boyfriend responds 'lmaooo' and the girlfriend spirals further: 'Why are they making ME cry??' She confesses she feels guilty walking ahead of them, like even she owes this girl an apology. Then she adds the kicker — she heard the sad song the girl was playing on her phone... and missed her bus.
