Both Peach Girl and Heroine Disqualified are about a girl and two boys and their love triangle. both are of the comedy/romance/school/shoujo genre. In both movies the main character (momo in peach girl/hatori in heroine disqualified) had a crush on her classmate (toji in peach girl/rita in heroine disqualified) for the longest time. Meanwhile, the most popular male student (kairi in peach girl/kosuke in heroine disqualified) suddenly appears and steals her first kiss and confesses her. Both movie have many smiliar scenes. For example, When the first boy break up with the girl, she crying in the rain and the second boy hugs her. If you like one, I guess you'd like the other.
