I am Jooyeon's younger sister and I just enrolled in college Gun-il is showing me around and we slowly start having feelings for each other but she can't tell her brother or can she?

Yeah when you lose feelings for someone you normally stop hanging out with them or talking to them all together, not in Jiseok's case. Instead, he had to face the sad path of becoming heavy enemies with his past crush Han Hyeongjun. Are feelings really gone? (Or Hyeongjun and Jiseok hate each other, or do they?)
