Jeong Tae-eul doesn't hate people. But it's easier to pretend she does. Abandoned as a child and adopted into a new family, Tae-eul has always kept people at arm's length. That is until her sister, Hayden, drags her into the "I Hate People Club," a university support group for the broken-hearted and disillusioned. The "I Hate People Club" was supposed to be her safe haven-a place to bury her fears, hide from her past, and steer clear of connections. But university is a strange place, and the club soon brings a cast of complicated, damaged people into Tae-eul's life, including Sebastian, the infuriatingly charming boy who seems to see right through her. As walls come down and secrets creep in, Tae-eul is forced to confront the very things she's been running from. But with each truth revealed, she wonders: how much of herself can she share before everything falls apart? When your past is built on heartbreak, can you ever really let anyone in?
