Touch

タッチ

Yamato Keisuke, a promising freestyle swimmer, and Ninomiya Ami, a talented diver, are the offspring of two rival families owners of confectionery shops. Two generations ago, Grandfather Ninomiya came up with an idea for an owl-shaped cake, but Grandfather Yamato quickly raised to the challenge and thought of a similar cake—but in Yamato's the owl had ears. Because they're priced the same, Yamato's extra ears were crucial, and that made the business of the Ninomiya confectionery suffered. Grandfather Ninomiya then fell ill worrying about his shop. Before his death, his last words were "I was killed by the Yamatos," and since that moment the two families have been sworn rivals.

In the town of Tokeizaka stands the old, worn-down boarding house known as Maison Ikkoku. For the last few years, the building has been home to a rambunctious group of tenants, including 20-year-old college applicant Yusaku Godai, its most recent resident. Recently, however, Yusaku has grown impatient with the noisy shenanigans interrupting his studies and has decided to move out. However, as he is preparing to leave, a beautiful woman named Kyoko Otonashi introduces herself as the new property manager. Falling in love with her at first sight, Yusaku changes his mind and decides to stay to court Kyoko instead.

Though he initially believes he is making progress with Kyoko, Yusaku soon discovers that she is a widow still mourning the loss of her late husband. Despite her growing feelings for Yusaku, Kyoko states that she has no intentions to remarry or even date, as she still loves her late husband. Empathizing with her, Yusaku seeks to free Kyoko from her sadness with the help of the other inhabitants of Maison Ikkoku—all in the hope that she will one day see him as more than just another tenant of the building.
