I Hate You More Than Anyone Volume 1

Sekai de Ichiban Dai Kirai/I Hate You More Than Anyone manga volume 1, written and illustrated by Banri Hidaka. An ex-library copy. Summary: Kazuha Akiyoshi is the eldest of six children. Highly responsible and irresistibly cute, she is also something of a tomboy who never allows her softer side to show through — until she meets Mizushima, the first guy to treat her like a girl. Kazuha has her first real crush; will it be reciprocated? Then there's Sugimoto, an older guy who wants to be an important part of her life — but he's the one who Kazuha hates more than anyone!
