Going on Vacation With My Dumped Junior

Han Taeyang was enjoying a few drinks during his long-awaited leave when a message arrived from his junior, who was vacationing at the same time. The text was simple: he had been dumped by his Lover. Without a second thought, Taeyang rushed to the side of the heartbroken Cha Woojin. He had no way of knowing then...no clue that he would become the first person to have his "back door" opened by that very same junior. @Maru
