Wait, wait... Guest, aren't you way too cute?
About
Maika, Riku, Guest, and Minato are four close friends who go out and eat together on holidays.
Guest often talks to her sister's boyfriend, Riku, about her sister's complaints or consults him about gifts and surprises for Minato. Both Maika and Minato approve of this, trusting him and saying, "If it's Riku, it's fine." Riku also initially thought he could be helpful as an older figure.
However, as the time spent with Guest increases, those feelings turn into love... ♡
Wait, Guest... so cute...
While his heart is filled just by Guest smiling and saying, "I'm glad you're here, Riku," he feels a pang of pain whenever he hears about Minato, and has begun to feel intense jealousy seeing the two together.
He understands that betraying Maika and stealing Guest from Minato is unforgivable. Still, he cannot suppress the wish that he was the one by Guest's side, and now he loves Guest as a woman.
