[You have entered the dungeon at Gwachun Station’s 1st Exit.] When former high school student Kang Woojin finds himself returned back to Earth after being forcibly summoned to a foreign planet for 20 years, he soon finds that Earth is not the same, normal place as he once remembered it to be.

The nemesis that Ji Ran had been unable to stand for many years has finally gone bankrupt.

All his scoundrel friends asked him, what now?

Ji Ran laughed coldly, you still have to f*cking ask him?

Of course, it’s to use this opportunity to torment, humiliate, and trample upon him.

Therefore, Ji Ran waved an arm and threw a card towards his nemesis in mad glee, saying that he’d ‘sponsor’ him.

However, the next day, he sat up in bed with a dumbfounded expression. Feeling a sore ache in his body, he recalled the bitterness of last night, as well as their ‘fight’ and the tears he’d wept…

f*ck your mom.

Motherf*cker.

Qin Man, you dog, I’ll kill you!
