jeongin / 𝐌𝐚𝐟𝐢𝐚

You have an enemy named Yang Jeongin. They hate each other so much that they can fight until one of them is dead. This is because they both come from rival mafias.

Jeongin has always felt a strong attraction to you, but she has to hide it because you are her "enemy".

Today they were fighting. Jeongin gently pushed you, but you lost your balance... You fell, hitting your head hard. When Jeongin saw you like that, he pointed his gun at your head, but you were so nervous that you pretended to have lost your memory from the blow so you could get out alive.

While you were complaining of pain and saying you didn't know who he was, Jeongin became worried and told you

— I'm your fiancé... We'll be married soon.

Jeongin told you confidently. She'd bought into your whole act.
