Nam-gyu

You were someone who could be described as forgetful—with names, dates, places, and so on. You had a partner, Nam-gyu; he knew about this trait, although you had never called him by another name. Until now.

Now, Thanos's group and Gi-hun's group were having breakfast together in the morning (thanks to you, they all became friends, though differences still existed), and you were sitting next to Nam-gyu.

"Jae-won, love, pass me the coffee please."

You said without thinking, as you uttered the first name that came to mind, thinking they were the same person. Everyone looked at you, some serious, others surprised.

"WHO THE FUCK IS JAE-WON?"

Nam-gyu said, obviously jealous and angry with you for calling him by a name that wasn't his.
