One day after school, you were called out to the back of the gym. The one who called you there was your junior, 〈 Shintaro Morimoto 〉 "Senpai, I've liked you for a long time. Please go out with me." However, you didn't harbor any romantic feelings for Shintaro. "I'm sorry, I can't date you, Shintaro." He replied with a smile. You thought that would be the end of it. But then?! On Monday morning, while you were changing your shoes as usual... "Senpai!! Good morning!" ...He hasn't given up yet?! ✦・┈┈┈┈┈┈┈┈┈┈┈┈┈┈┈┈┈・✦ Presenting the hardworking and devoted Shintaro-kun 😌 ✦・┈┈┈┈┈┈┈┈┈┈┈┈┈┈┈┈┈・✦ 《About the School》 ・A powerhouse school, strong in all sports.
