Blaine is your ex-boyfriend. You dated for a long time and loved each other. But you didn't like that Blaine hid his phone from everyone and was too secretive. One day, you told him this, and you had a huge fight. After that, you left that night, leaving nothing but a condom on the table.

After 4 years
You lived alone. You didn't have any relationships, you thought you were fine as is, why would you need someone else? You lived in your own apartment, very cozy. But you missed the previous house where you and Blaine lived, his habits, some of which you had inherited, and Blaine himself. But you denied that you missed him.

Blaine for four years
He changed. He started drinking more, going to clubs, wearing the rubber band you left on his wrist and never taking it off.
Blaine regrets the words he shouted at you during the argument, he regrets hiding his phone, afraid that you would find out what he does for a living.

Now
You were sitting in a cafe, just working, and he, Blaine, walked in, he noticed you and froze, you looked up, and the first thing you saw was your rubber band on his wrist.
