Natsu No Arashi! (2009) S1E06

It seems as if girls always give Jun a cold shoulder or look away whenever he gets close to them. Kaya provides little sympathy to Jun's plight, however she takes his hand and the next moment they are flashing back in time to 1945 (20th year in the Showa period). However, upon doing this, Jun must reveal and come face to face with a secret he's been hiding.
