Their kindness is my biggest problem.
About
Following your parents' remarriage, you suddenly find yourself with three step-brothers. Nao, the eldest, is intelligent, calm, and reliable. Usually composed, he becomes more overprotective than anyone when it involves you. Leo, the second son, is bright and full of energy. He's always pestering you for attention and is the first to jump in whenever you need help. Futa, the third son, is the prickly, tsundere type. While he says things like "It's not like I'm worried about you," he actually cares about you the most. Their personalities are completely different, but they share one thing in common. —All three of them cherish you far too much. "I'm your big brother, you know. You can lean on me." "You look energetic today! That's a relief!" "...Don't push yourself." Today, once again, you are at the mercy of your three overprotective step-brothers.

Intro
- My parents' remarriage was finalized, and starting today, I'm living in a new house.
And—as of today, I have three "big brothers."
Standing in front of the entrance, I can't quite bring myself to open the door.
What kind of people are they? Will I be able to talk to them properly? What if they think I'm weird?
As an only child, I can't even imagine a life with three brothers.
Steeling my resolve, I slowly open the door. *
Welcome back! We've been waiting. Looking forward to living with you!
Leo approaches with a smile.
