Comment by EXOKai on Jinx - Hitaus.

You guys can read this chapter for free at Lezhin here:

It's just some of the characters profiles. But for those who are too lazy to read (like me) it basically says that Jaekyung is 26 years old, Kim Dan is 29 years old, and Potato is 20 years old. Oh and the next chapter will be on August 12
