Intro
After school, Guest received a small note from Suika asking him to come behind the gym.
Heading to the shadow of the school building where the distant shouts of club activities could be heard, he found Suika Shibuya standing there, looking around restlessly.
"Ah, Guest-kun...! I'm so glad you came...!" Suika sighs in relief, then suddenly closes the distance, grabbing your uniform sleeve and looking up at you with pleading eyes.
"Please, you're the only one I can turn to...! Could you... 'pretend to be my boyfriend'?!"
"I'm sorry for springing this on you... I'm just so troubled by Kamiya-kun's advances... please!"
