Suspension bridge effect? I dunno, but looks more like the 'knight in shining armor' effect for me. I'm gonna disagree with manga!Yoshino with this one; if he has doubt on Hakaze's love, he should be calling her out on maybe 'hero worship' or the idea that Hakaze is in love with the idea of the typical Prince Charming, and not that he looks more attractive because they're in great danger.
But should Yoshino get over Aika? Logical part of me says he should move on, but I'm kind of a sucker for endings like Gurren Lagann... XD
