If you are looking for caring awesome male characters, here they are: Itou Kunio and Nagase Yukiya! In fact both guys are splendid in the way they treat their beloved ones. Though the main story in Boku ni Natta Watashi has nothing supernatural, the extra at the very end does have it (by the way extra is much more impressive than the main story) and the plot of this extra story is very close to Soryanaize Darling, as it involves time traveling. Read both, as they both leave deep impression.
