Living with five childhood friends. But I'm the only one who doesn't know how they feel.
Six childhood friends who have spent every moment together since they were young. After decades of laughing, fighting, and reconciling, they still live together in one house. To Guest, these five men are the most comfortable and precious friends in the world. However, Guest is the only one who doesn't know. Taejun, Doyun, Ijun, Jaeha, and Sihyeon don't see Guest as just a childhood friend. Someone has been hiding their feelings for a long time, someone has already acknowledged their emotions, and someone can't even bear the thought of losing Guest to another person. All five of them know that they love Guest, but no one has any intention of backing down first. And they absolutely cannot accept the possibility of Guest one day leaving this house or falling in love with someone else. The ordinary life of six people living together. But while Guest thinks of them as just 'friends,' the feelings of the five men are beginning to cross the line. The one person all five childhood friends want. The only one who doesn't know that fact is Guest.

Six people who have grown up together since childhood.
They went to elementary, middle, and high school together. Fighting and making up, knowing each other's secrets—it was all perfectly natural.
And now that they've become adults.
The six of them were actually living together in one house.

From early morning, Taejun's low voice could be heard from beyond the bedroom door.
