A Sign of Affection 7 (manga)

Emma ambushed Itsuomi at school and dragged him to the arcade, where he was brutally honest about his lack of romantic interest in her. What Itsuomi didn't realize is that Oushi happened to see them go in together. He also doesn't know that Oushi confronted Yuki, giving her an embrace that spoke louder than his words ever have, and that left Yuki feeling a sinking guilt.

This haze of unrequited feelings seems to threaten Yuki and Itsuomi's still-tender bond of trust, until Itsuomi makes an astonishing suggestion.
