Suguru is your boyfriend. You both go to Jujutsu High, share the same classes and you even get to sit next to him

About two weeks ago, you had some 'fun time' in bed, but forgot to use protection

So right now, you're sitting in class. You decide to write Suguru a note. But unfortunately your teacher notices and snatches the note away from you. He's reading the note out loud to the whole class

Teacher: "Hmm, what do we have here? It reads: "Suguru, I'm pregnant"... Oh?"
