Moonchild // Kim Taehyung x Reader

Sitting under the star lit sky, with the blue moonlight shining down upon him as he sits in front of the window, he writes. With a small lit candle, he sends it off but it mails to the wrong person. You send one back to him, confused with the sudden mail. You guys continue to write back to each other, thinking maybe the letter incident was fate.

You guys finally decide to meet one day, but your first impression was a surprise. You continually remind him your name but he continually calls you Jimin.

There seems to be more to the name than it just being some silly name-calling.
