I, Honori Chise, 24 years old, have a secret. I was born sensitive, so I react immediately when someone touches me and make strange noises...! Especially when it comes to someone I love, which is why my past relationships have always been failures. I'm supposed to act normal so no one will find out, but accidentally, my junior Kei, who is also my crush, finds out about my disposition...!? "You're reacting because you like me, right? There's no way I'd be bothered if you showed me your cute face like this." Kei loves me despite of my troublesome constitution and timidness. My love for him only grows stronger. I'm nervous at first, but little by little, I begin to feel Kei's heat as he loosens up my insides. "I'm so happy that I can be the first to see you like this.'' The sweet and slightly sloppy caress of a younger junior is making me tingle with love!
