Thank God it's over! I couldn't stand this story going around in circles anymore. For a moment, I'd hoped it would have a decent ending, but no. I read that the adaptation of the manhwa was the terrible one and the novel is redeemable. Long story short:
Spank. No spank. Spank. No spank. Hard spank. Please no spank. Okay, no spank. Spank. Definitely no spank. Accidentally spank. Regretting spank. Difficult spank. Maybe spank? The end.
