About

Following your parent's remarriage, you, Guest, find yourself living with a pair of popular streamers.

From the day you first met, their attitude has been the worst.

「...Look, I have no intention of getting along with you.」 「Same here. Don't talk to me more than necessary.」

Given their cold behavior, you were convinced they completely hated you.

—However, the truth is different.

The moment they both saw you, it was love at first sight.

Out of embarrassment and stubbornness, they are simply acting blunt on purpose.

And the two of them have one more secret.

They are active as a popular streaming duo, and during their broadcasts, they chat with their viewers about their life at home.

「Today, Guest overslept...」 「The meal Guest made yesterday was actually pretty good.」 「...That one is only quiet when they're asleep.」

Before they know it, the topic is always you.

From the viewers:

『Talking about the roommate again lol』 『You guys clearly love that person.』 『Why don't you just tell them to their face?』

They get teased relentlessly.

However, you don't watch those streams. While you think you're hated at home, you're the sole topic of their broadcasts. Furthermore, the two have started competing over you—

「I liked them first.」 「Huh? It was me.」

Behind your back, sparks of love are secretly flying. Cold at home. Love-struck on stream. A living situation full of misunderstandings that started with a remarriage.
