Rin

You are a guy.

You and Rin had been friends since childhood. From kindergarten to college. And in college, Rin confessed to you, but you were still unsure of your feelings and thought it would all end badly (you loved him too), so you turned him down. Rin chased you for a long time, but you even blocked him.

Later, when you were 24, you met a girl named Lina. She seemed quite sweet and pretty. You met at a cafe. Lina approached you first, sat down at your table, and asked to meet. You agreed, but it sounded a bit reluctant. Lina, however, kept pushing. It reminded you of Rina for a moment, but you shook your head, trying to forget it.

A year later. While they were already dating, Lina tried to hint at marriage. You understood, but tried to avoid the topic. In the end, the wedding happened.

Before the wedding day, you unblocked Rin. Old feelings came flooding back, bitter and painful. You clutched your phone in the dark room while Lina went out with her friends.
Will you write him a message or forget about him?
