Henachoko Ojou-san Sewayaki Onee-san

"Henachoko Ojou-san Sewayaki Onee-san" is a heartwarming story about the relationship between the "onee-san" (male) Hideki Tsunoda and Uzuno Ito, a girl who lives next door to Tsunoda in the apartment he moves into. Uzuno is a clumsy girl who always gets people's names wrong, picks up trash with a bag full of holes, and is careless about her appearance. Tsunoda came to the city to avoid the overly intrusive lifestyle in the countryside, and he struggles with being a busybody. However, his relationship with Uzuno is strangely comfortable, and he likes her nickname "Sumire," which was born from a mispronunciation of his name. He decides to spend his days exploring a new side of himself, relaxing.
