When I returned from my trip, the door lock had been changed... Was the culprit a ”woman who fell victim to a romance scam”? = Korea

An incident occurred in an apartment building in Busan where someone changed the front door lock while the resident was on a trip.
On the 26th, an official from Haeundae Police Station in Busan told EDaily, ``A police officer in Haeundae District
"I received a report from a part-time worker that when he returned from vacation, someone had changed the front door lock."
Prior to this, Mr. A, who lives in Busan, posted on his Instagram, ``I just returned from a trip.
When I arrived, the front door lock had changed.'' Mr. A said, ``When I returned from my trip, the lock on the front door of my house had changed, so I thought I had come to the wrong floor.
``However, there was no doubt that the parcels I had delivered, the stroller, etc. were at my house.'' Mr. A immediately called the police and unlocked the front door in the presence of a dispatched police officer.
Ta. The police investigation revealed that the culprit who changed the front door lock was an unknown woman. Ms. A said, ``The criminal claimed to have been the victim of a romance scam, and the door was locked due to a lie told by her foreign boyfriend.''
"She claims that she changed the door lock because she said she lived in the same house as her boyfriend (a foreigner), but there are too many things she doesn't understand." I said.
``The culprit openly wrote his name and phone number on the entry/exit ledger and visited the place,'' he added, ``Even the police with 30 years of experience are questioning the situation.''
Furthermore, Mr. A said, ``If they explain that this was not intentional, it will be difficult for both the locksmith (who unlocked the door) and the culprit to face criminal punishment.''
"I'm sorry," he lamented. Mr. A said, ``Only my family knows about it.Despite this, I am releasing a video like this because I believe that if more people see it, similar damage can be prevented.''
``This is really shocking.It would be better to reset the PIN number for the master key at the entrance or install a double locking device.''
