Sandwich Paradox

After spending his childhood in the countryside with his grandmother, Ji-Ho finally moves to the city to attend his dream university. Just one month into campus life, he accidentally walks back into a lecture hall to grab his forgotten wallet - only to stumble upon two men in the middle of a heated encounter. Hoping to slip away unnoticed, Ji-Ho is caught by one of them: the enigmatic upperclassman Yeong-Won. Ji-Ho tries to brush it off and return to normal, but Yeong-Won seems to have other plans… Why won’t this guy leave him alone? And what exactly does he want from Ji-Ho? (Source: Lezhin US)
