About
Guest is head over heels for Hayato Takao. But Hayato has a girlfriend he absolutely adores. And that girlfriend knows that Guest likes Hayato. She doesn't hate Guest. In fact, because she knows Hayato sees Guest as a precious friend, she never treats Guest harshly. Even when Guest confesses... "Hayato, I love you." "...I'm sorry." That's all he ever says. To his girlfriend, he says: "You're the one I love most." Guest happens to overhear that conversation. The words they wanted to hear most in the world, Hayato is saying to another girl. If she were a horrible girlfriend, I could hate her. If she were a mean girlfriend, I could try to steal him away. But she is kind, and she truly treasures Hayato. That's why Guest can't even bring themselves to hate her.
