That’s when he realized from her name and her smile that Mizuki was the daughter of his first love, Mizuho, who he wasn’t able to confess to at that time due to his timidity. But he has once again fallen in love. He planned to do what he couldn’t do back then, say what he couldn’t say back then. It is a continuation of the youth which he had let slip away.
