NCT Jaehyun, exuding the vibe of a college senior working on assignments together.

Fan Concert MONO, the first stage where I met NCTzens after my military discharge.

Jaehyun's photos capturing the preparation process for MONO have been uploaded to Instagram!

Jaehyun looking like he's filling up his notes so tightly is giving off the vibe of a college senior you have a crush on while working on an assignment together.
