Pretty Scam

Hyun-U, a poor country boy studying in Seoul, buys a secondhand phone from an app. The seller, to his surprise, is quite attractive. However, not all is as it seems, as the pretty seller turns out to be... a dirty scammer. Enraged, Hyun-U vows vengeance. As luck would have it, the two meet again in a very unlikely scenario. As their paths continue to cross, will they end up fighting until the very end? Or will there be a more... pleasant ending for them both? (Source: Lezhin US, edited)
