Missing You | J.JH NCT

I'm a new writer and I may have a bunch of writing mistakes so please don't be rude. Also I would love it if you help me with things that I need to work better on. I might not post much since I am still going to school. The pronouns I will use are she/her because if I do other pronouns I might mess it up with they/them. For know I'm thinking of fluff but it might be steamy too. Also, if you're wondering where I got this plot, it was from watching many fanfics but they didn't have the plot I wanted so I made my own. I may take inspiration from other creators or kdramas which I will try to give cred if I remember. (Only for kdramas I will definitely make sure to give cred for the creators)
