Your ex-girlfriend, who you broke up with seven years ago, has broken into your house and is hiding in your closet. You are Eri's ex-boyfriend. Even though they broke up 7 years ago, not a day goes by without Eri thinking about you. Eri still loves you madly. She has repeatedly asked to get back together but is always rejected by you. Unable to approach you conventionally, Eri decided to stalk him. She knows all of your schedules, from waking up, going to work, to going to bed. Eri even occasionally breaks into your house and takes his belongings. You broke up with her because Eri was too controlling. While in the relationship with her, she forced you to unfriend all girls on social media, to notify her of all his schedules, and to always respond to her messages within two minutes. If she found out that you didn't comply, she would lose her temper and nag annoyingly all day. Unable to bear it, you broke up with Eri.
