Accordingly, a couple had a dispute that led to them arguing right on the pedestrian street. Although the guy was very angry, he couldn’t bring himself to raise his voice at his girlfriend. So he could only slap himself to vent and regulate his emotions.

Seeing her boyfriend punish himself like that, the girlfriend softened and tried to stop him. One person wanted to slap himself, while the other wouldn’t let him self-harm. The scene caused passersby to misunderstand, thinking that the couple was fighting each other.
Indeed, a man passing by mistakenly thought that the guy was hitting his girlfriend, so he eagerly intervened “in the name of justice.” Accordingly, he approached without saying a word and gave the “main character” a beating.
The couple was extremely stunned at that moment and didn’t understand what was happening. The girlfriend saw her boyfriend being attacked for no reason and tried to stop the man.
After hearing the girl explain the situation, the guy realized and felt embarrassed for being too aggressive in interfering with someone else’s business.
Seeing him continuously apologize, the young couple didn’t hold a grudge and even thanked him in return for his actions stemming from good intentions. If there really had been a scene of violence on the street and he had intervened, the girl would surely have been very grateful.

Many people believe that although the action had good intentions, it was still very inappropriate. If the brother had initially intervened by calmly asking about the situation instead of “getting physical,” everything would have been different. “Intervening in the name of justice” but making a grave mistake was seen as meddlesome, “well-meaning but not considerate, enthusiastic but destructive.”
Additionally, many netizens praised the brother for acting righteously to help someone in need. Although the outcome was just a misunderstanding, it was still worthy of community criticism.
“The brother’s actions would be commended if he had handled the situation more appropriately, rather than in such a rough manner. Although the couple didn’t pursue the matter, the guy probably endured quite a bit of hardship being punched for no reason like that.”
“Fortunately, the guy wasn’t seriously injured; otherwise, his good intentions could have turned into disaster.”
“In any case, the couple didn’t show any negative attitude, so the online community should overlook the brother’s mishap and focus on his good intentions instead.”
