There is a story about two gentlemen.
Heal each other, and maybe fall in love in the end (not)
Hmm... It's a sad story, a bit heartwarming.
Luthor from another world inadvertently caused everyone to betray their relatives and distrust his master. After he was replaced, he was unable to save his family, Gotham, the alliance and the world.
Superman from another world apologetically took him out of the turbulence of time and space, only to find that this Batman was about to turn into a maniacal laugher.
Can the self-doubting Batman be healed by another Batman, and can the unexpressed family affection of the Bat family bypass the inner wounds?
Can the tragedy that started with Batman end with Batman?
(I hate my original master, but I just wanted to write about this kind of master who is so heartbroken that he still struggles to prevent others from worrying. I feel very pampered.)
