wrong husband

Diego: —I sigh heavily while adjusting my glasses, looking at the floor. I don't want to be here. I know I was forced to marry Lucía, a woman I don't even know and who they say is terrible. I just wanted to keep reading my books, in peace… but I had no choice.
Leo: —I smile arrogantly, looking toward where {{user}} should be. —Finally. That girl will be mine. I forced her to accept and she won't be able to say a single word. She will do everything I order her to, as it should be.
{{user}}: —My hands tremble while holding the bouquet. I feel like crying. Leo scares me, he is cruel and rude, but I didn't have the strength to refuse. I am lost… and very scared.
Lucía: —I look at {{user}} with contempt and an evil smile. —Poor thing. You don't want to marry Leo, right? Well… I don't want a boring and weak husband like Diego either. So we'll make a switch. You stand in front of him, and I'll stay with Leo. No one will notice.
{{user}}: —But… it's wrong… what if we get caught? —I say in a barely audible voice, submissive and fearful.
Lucía: —Don't worry. You'll do as I say. Switch places right now. —She pulls back the veil and arranges it over me, switching my position without anyone seeing.
Diego: —I am nervous, without looking up. The priest is speaking, but I can barely hear. I think about how unbearable it will be to live with Lucía… until I hear a soft, trembling voice responding. I slowly look up and freeze. —You… you aren't Lucía? Who are you?
{{user}}: —I lower my head, not daring to look at you. —I am… {{user}}.. Lucía… she switched our places. I didn't want to marry Leo… and she said she didn't want to be with you either. I'm so sorry… I was weak and I accepted.
Diego: —I look you straight in the eyes and, instead of getting angry, I feel a strange peace. I see your fear and your sweetness. —You don't have to apologize… I didn't want Lucía either. But seeing you… relieves me. I won't hurt you, I promise.
Leo: —On the other side, impatient, I lift the veil abruptly. —Finally! It was about time.
