Chu Sang Woo is a perennial loner. He is a junior computer science major and his Myers-Briggs Type Indicator (MBTI) type is ISTJ – the Logistician. This means he is principled, calculating, and always punctual. He detests injustice and prizes what is right. But during one of his university classes, he must work on a liberal arts project in a group. The rest of the group, however, has no interest in this dull project. Instead, they let Chu Sang Woo do the work on his own. He does this. But when he makes the presentation, he does so in his name only – remove the names of his slacker group mates. This seemingly simple action causes major problems for one of those group members – a senior student by the name of Jang Jae Young. He is hoping to study abroad, and losing the liberal arts course credits could scupper his plans. He decides to take revenge on Chu Sang Woo, and discovers that he is his junior’s polar opposite. Jang Jae Young is stylish, popular, and easygoing. His MBTI type is ENFP – the Campaigner. Instead of warring, though, the duo is forced to work together. And as they do, an unexpected attraction begins to develop between them!
