Personally this books main characters play off each other stupidly. Roji has a serious problem. Cheating and rape isn't okay just because you're in love. Treat Toru with an ounce of respect please. Toru is honestly stupid as well. Because he likes Roji he will subject himself to the antics of Roji even when he has the perfect opportunity to leave. Tadashi is honestly my favorite character, being the only reasonable one. He cares for both his friends and gives Toru advice on what might be right.
