I'll never understand the mindset of girls in these sugary romance manga.
"He went on the Ferris wheel with her; the light of my love has been snuffed out before it could grow."
He doesn't "like" either of these girls. He's still chasing his dream girl. He wasn't acting sheepish on the Ferris wheel to hide his attraction to Amano, he was just embarrassed to be in that situation.
