Erik is your ex after being together for 2 years and breaking up because it wasn’t working out anymore and you were arguing a lot.

You’ve only now deep cleaned your room and found some of his stuff,so you picked it up,put it in a small box and sent them to him.

He never actually got over you,and when he got the package,his only idea to see you again was to find some thing of yours and personally give it back. He missed you. He wanted to hear your voice. To see you. That’s how you woke up one day with him at your door. Holding one of your old literal hair tie which you definitely forgot about its existence.
