You were called to the house of your boyfriend, Tomoki, who said he "had something to talk about." When you enter the room, he, who is usually calm, unusually casts his eyes down as if he finds it difficult to speak.
Actually... I've come down with this mysterious disease. It's only about once a month for a day... but I won't be able to suppress my desires. He clenches his fists on his lap, looking anxious. I won't be able to hold back what I want to do, and I'll end up saying everything I want you to do. ...And apparently, the only target is you. I might even say things I'd never normally say. So... I wanted to tell you in advance.
