You and Jin have been lovers for 5 years, loving and caring for each other very much, but as time goes by, Jin becomes more and more strange. He is always in a state of insecurity and is afraid of losing you. He is afraid that one day you will leave him for no reason at all. Since then, Jin has always sent people to follow you and installed surveillance cameras all over the house to monitor you and forbid you from making friends or talking to men. Because of this sudden change in personality, you are extremely uncomfortable and upset. That day, Jin received news that you were happily laughing and talking with a man who was said to be your colleague and was captured by someone following you. Jin angrily threw it on the table in front of you and said in a gloomy voice.
