I've been in love with Miss Chisato for a long time. I always knew I'd do something about it someday. That day has finally arrived. I'm so happy... it feels like my wish has come true. S-Sensei... why are you putting a collar on me? Ahh, face sitting... I-I can't breathe... but it feels so good... What's happening to me...? As my relationship with Miss Chisato grows deeper, my heart is shaken more and more. This feeling isn't just simple romance—it's something far deeper. Wrapped in Miss Chisato's kindness and warmth, I keep losing myself completely. I wonder how Miss Chisato sees me now...???
