10 Slice of life romance anime you must watch.

1. Horimiya.

Kyouko and Izumi are two classmates who each lead a double life: the popular and talented Kyouko cares for her little brother by herself while her parents are away, and the quiet, bespectacled Izumi hides his many piercings and tattoos at school. After accidentally discovering each other's secrets the pair becomes fast friends, and together, they begin to navigate their new relationship together amongst unknowing peers and love rivals alike.

2. Ao Haru Ride.

Futaba Yoshioka used to be an attractive and popular middle-schooler—well liked by the opposite sex, but ostracized by the girls. Nevertheless, she was able to brush all that off, because the only opinion that truly mattered to her was that of Kou Tanaka, a classmate with whom she shared a shelter from rain once, followed by quite a few other precious and significant memories. She even succeeded at making plans to meet with the quiet and innocent boy at the summer festival, but a simple misunderstanding, and Tanaka's subsequent disappearance, left her walking the halls of her school friendless.

Now in high school, Futaba is not your typical adolescent girl. Determined to become a class favorite this time, she avoids all unwanted attention and, instead of acting cute and feminine, only stands out through her tomboyish behavior and disheveled look. But still, her world is soon turned upside down when the only boy she ever liked unexpectedly comes into her life once again—except he goes by the name of Kou Mabuchi now, and it is not his name alone that has gone through a sea change.

Taking it without a second thought, Arata awakens the next day to find that his appearance has reverted to that of a 17-year-old.

Arata soon learns that he is now the subject of a unique experiment and must attend high school as a transfer student for one year. Though he initially believes it will be a cinch due to his superior life experience, Arata is proven horribly wrong on his first day: he flunks all his tests, is completely out of shape, and can't keep up with the new school policies that have cropped up in the last 10 years. Furthermore, Ryou has been assigned to observe him, bringing Arata endless annoyance. ReLIFE follows Arata's struggle to adjust to his hectic new lifestyle and avoid repeating his past mistakes, all while slowly discovering more about his fellow classmates.
