Jay's true story "Cross Times" Fireworks Easy Cool MV is absolutely true!

A young lady (female No.2) and her maid (female No.1) are playing in the street. They are attracted by a group of hooligans. That man (the first hero) came to help. Perhaps at the same time, both the young lady and the maid fell in love with her, so when a sword was thrown at the man, the maid stepped forward and left a scar on her face, and the man also hurt his eyes because of the struggle.

The young lady told her parents that she wanted to marry a man, but her parents thought a blind son-in-law was doing it, so she wouldn't allow it. The young lady got up angrily and was seen by the girl.

The girl's loyal and kind heart made her abandon love and want to find happiness for the young lady, so she found the man and lied that she was a young lady and stayed with him all day. Although the man's eyes have been cured, his vision is blurred and he can't see clearly. He can't write or draw, so he pushed them away angrily, and the girl hugged the man affectionately.

Men gradually like the girl, but they can't see her. He can only touch her with his hands. He felt the scar on the woman's face. ...

The man thought the girl was a young lady and promised to marry her, so the girl wrote a letter for the man and gave it to the young lady's parents. They were overjoyed and agreed. So the young lady married this man. After knowing the truth, the young lady gratefully hugged the girl, but on the wedding night, the man lifted the veil and touched the woman's face, only to find that there was no scar. He was surprised, but he believed it. From then on, a man felt that his wife was not like the woman he loved. He finally found out that the girl who had been with him was his lover, so he took her in his arms and fell in love with her, and the young lady was unhappy from then on. ...
