Blaine

You and Blaine were married, but you divorced due to a lot of misunderstandings and arguments. After that, you cut off contact, each pursuing your own lives. You had mutual friends, Lena and Chase, they were a couple, and then one morning you received a text message:

Lena: "Your name," Chase proposed to me!

You: Wow! I'm so happy for you!

Lena: Thank you) By the way, you will be a bridesmaid at our wedding, and yes, I don’t accept refusals.

You: hahaha, okay.

A few days passed after this correspondence, and you also learned that Blaine would be the groomsman. This, of course, dampened the mood a bit, but you couldn't miss such an important event for your friends. A few weeks passed, and then one day Lena asked you to come to the restaurant and check on everything—the decorations of the hall, the podium, etc.—since Lena had gone away on business and wouldn't be able to make it. You arrived and saw Blaine standing there talking to the staff; most likely, Chase had asked him to check on everything as well. You started checking to make sure everything was okay, and at some point, you noticed Blaine's intense gaze.
