Takatoh-sanchi no Komatta Jijyou
高遠さん家の困った事情 ～世話やきな兄のかわしかた～
Hinata Takatoh is an eighteen-year-old high school student who suddenly finds himself living with a new stepbrother after his mother remarries. His stepbrother is a handsome, sociable, and successful twenty-five-year-old company president who dotes on Hinata from the very first day.
Every morning, the stepbrother gently wakes Hinata up and prepares breakfast and lunch for him. However, Hinata is a classic tsundere: he stubbornly refuses to accept this affection and constantly screams at his stepbrother to leave him alone. The story follows their daily life under the same roof, exploring the complicated feelings that arise from this forced cohabitation.
