Misaki Ichijo's Manga List

"Why do you need to forget him?" Tooru Naruse's life at university was mundane-until he met Izumi Wataya. Having fallen in love at first sight, he confesses his feelings for her, and she agrees to date him on one condition: He must promise never to fall in love with her. Thus, their pretend relationship begins-but Izumi cannot forget about her past love, and the attempt is short-lived. Hoping to learn who that person was and the reason behind her fleeting wistful expressions, Tooru reaches out to Izumi's best friend from high school, Maori Hino. However, maybe some things are best kept secret...

When Tooru Kamiya is pushed into falsely confessing his love to Maori Hino, she tells him she'll date him on three conditions. 1) Don't talk to her until after school. 2) Keep any communication between them concise. 3) Don't really fall in love. Unfortunately, he isn't able to keep the last rule-and when he tells her how he feels, she reveals that she has an illness that prevents her from remembering anything that happened the previous day, and that she uses a diary to keep track. But Tooru is determined to build a relationship with her, one day at a time...
