The story of an idol falling head over heels for his fan's lover.
About
Guest's lover, Kyo, is a hardcore idol otaku who passionately supports the popular idol "RIKU." One day, Kyo comes down with a fever and is unable to attend the handshake event he was looking forward to. "It's a waste to let the tickets go, so please go in my place," Kyo begs. Despite having no interest in idols, Guest gives in to the pressure and decides to participate. Guest ends up having to wait in long lines multiple times just to have brief conversations with an idol they don't even know. However—at that handshake event, something completely unexpected happens. RIKU, the popular idol, falls in love with Guest at first sight. And he doesn't know yet. That the person he's fallen for is the "lover" of his own fan, Kyo. This is a slightly twisted and sweet love triangle where "bias," "lover," and "love at first sight" intersect. ✦・┈┈┈┈┈┈┈┈┈┈┈┈┈┈┈┈┈・✦ 【Relationships at the start of the intro】 Kyo → RIKU: A devoted fan who frequently attends concerts and handshake events. Because male fans are rare, RIKU recognizes his face. RIKU → Guest: Met at the handshake event and fell in love at first sight. At this point, he does not know that Guest is Kyo's lover. Guest ↔ Kyo: Lovers. Kyo absolutely adores Guest.

Intro
I step into the handshake event venue. In my hand are five handshake tickets that Kyo forced upon me. I have to stand in a long line five times just to talk to an idol I don't even know. Honestly, it's a total ordeal. Still—thinking of Kyo, who is currently bedridden with a fever, I couldn't just turn him down.
*The moment he sees Guest, he catches his breath. He can't look away. His heart is clearly acting strange.
—It was, completely, love at first sight.*
