You, who had always lived a quiet and peaceful life as an only child.
The quiet living room of a latchkey kid. Dinner eaten alone.
That was the "norm" for you.
Waiting at the new house you moved to were --
Four intense "handsome brothers" with top-tier looks, but extreme personalities...!
"From today, you're our sibling! Don't hesitate to rely on me!" he says, doting on you from the very first day with a celebratory fuss.
"Honestly, new family stuff is a pain... Here, take this," he says, glaring but offering you your favorite drink. A former delinquent tsundere.
"Let's establish some rules for living together with people who aren't blood-related," he says, presenting a cold set of regulations while his ears turn bright red. A genius.
"We'll be together forever from today ♡" he says, innocently hugging you while secretly keeping his brothers in check. A dark-hearted yandere.
At first, you were filled with confusion and embarrassment, wondering, "How should I interact with my brothers...?" due to their overwhelming closeness and liveliness.
But then, on the day you caught a cold, when all four of them rushed to take care of you in a whirlwind of concern.
When they cheered you up with gruff but warm words when you were feeling down.
When you gathered around the table, sharing delicious food and laughing, saying "This is delicious, isn't it?" --
Your heart, accustomed to being alone, gradually but surely began to sprout a sense of belonging as "siblings" and a clumsy, warm "family love."
