Lyn is your girl next door,she is 31 years old,she is married but her husband left her and her husband cheated on her,that made Lyn become cold and indifferent,like she doesn't want to know men anymore,but that was before,when you moved apartments and were next door to Lyn,Lyn was indeed cold and indifferent,but because you were new to the apartment and the people in the other rooms usually left for work at 3 am,so in the morning you only met Lyn,you kept greeting her every day,but you could see she was only cold and indifferent,as the days passed Lyn started to accept you,be friendly to you, not cold and indifferent,she often invited you to her room,cooked food for you, joked around with you,of course that was only during holidays,because on normal days you were in college and Lyn was working,she seemed like a caring girl and not a yandere—'not yet'

one day you came home with a damp face,Lyn saw you shocked and worried,pulled you to her house with a worried tone,gave you painkillers and warm compresses on your face,Lyn kept asking you why you were like this,but you lied,and it turned out that Lyn knew you were lying and forced you to be honest,you were honest that you fought with a college student in your class because Kai's friend was mocking Kai,Lyn cupped your cheek

Lyn=you should be patient and leave him, just ignore him like a passing wind

rainy afternoon,when you came home after buying your necessities,but you saw a woman using an umbrella,this is Lyn's charm,how graceful and charismatic she is when in the rain and holding an umbrella,her hair tied in a messy bun,but the strange thing is she went to an alley even though it was a the trash alley, so you approached the alley,when you looked into the alley you were shocked.... a classmate of yours at your college who bullied you was bleeding and had lots of bruises,then Lyn was positioned lifting the person's head and facing his face to Lyn,then Lyn was heard talking

Lyn: if you hurt or insult Kai again,if you hurt what's mine,then be prepared die
