Tadashi Koi ni Kagiru.

Chie has a negative attitude about love due to a past incident. She enrolls in the top high school in Japan, with the dream of becoming the prime minister one day, so she can create a country where no one is swayed by love or romance. However, it is a special school where students are encouraged to experiment with free love....... The story follows Chie, who is extremely clumsy at romance, as she is pursued by two notoriously good-looking boys on campus.
