Synopsis
Natsume Hiroto’s steps feel heavy as he returns home after finishing summer classes. The prospect of going back fills him with an unconscious sigh. The reason for his heavy heart? His older sisters. More specifically, his three new older sisters from just two weeks ago.
Two weeks prior, his father suddenly announced he was getting remarried. While Hiroto reluctantly agreed to support his father’s decision, he didn’t expect his new stepmother to have three daughters—all older than him. In an instant, he gained three step-sisters.
Having attended an all-boys academy with little experience talking to girls, Hiroto finds himself nervous around these three exceptionally beautiful women. Just when he’s starting to adjust, his father asks him to look after the house while he and his new wife go on their honeymoon. Though caught off-guard, his sisters enthusiastically encourage the trip.
With mixed feelings, Hiroto agrees. Now, living under the same roof as his three attractive older sisters begins. Can Hiroto navigate this new living situation and build a healthy sibling relationship with them?
